Add a new future.v7_relativeSplatPath flag to implement a breaking bug fix to relative routing when inside a splat route. (#11087)

This fix was originally added in #10983 and was later reverted in #11078 because it was determined that a large number of existing applications were relying on the buggy behavior (see #11052)

The Bug The buggy behavior is that without this flag, the default behavior when resolving relative paths is to ignore any splat (*) portion of the current route path.

The Background This decision was originally made thinking that it would make the concept of nested different sections of your apps in <Routes> easier if relative routing would replace the current splat:

<BrowserRouter>
  <Routes>
    <Route path="/" element={<Home />} />
    <Route path="dashboard/*" element={<Dashboard />} />
  </Routes>
</BrowserRouter>

Any paths like /dashboard, /dashboard/team, /dashboard/projects will match the Dashboard route. The dashboard component itself can then render nested <Routes>:

function Dashboard() {
  return (
    <div>
      <h2>Dashboard</h2>
      <nav>
        <Link to="/">Dashboard Home</Link>
        <Link to="team">Team</Link>
        <Link to="projects">Projects</Link>
      </nav>

      <Routes>
        <Route path="/" element={<DashboardHome />} />
        <Route path="team" element={<DashboardTeam />} />
        <Route path="projects" element={<DashboardProjects />} />
      </Routes>
    </div>
  );
}

Now, all links and route paths are relative to the router above them. This makes code splitting and compartmentalizing your app really easy. You could render the Dashboard as its own independent app, or embed it into your large app without making any changes to it.

The Problem

The problem is that this concept of ignoring part of a path breaks a lot of other assumptions in React Router - namely that "." always means the current location pathname for that route. When we ignore the splat portion, we start getting invalid paths when using ".":

// If we are on URL /dashboard/team, and we want to link to /dashboard/team:
function DashboardTeam() {
  // ❌ This is broken and results in <a href="/dashboard">
  return <Link to=".">A broken link to the Current URL</Link>;

  // ✅ This is fixed but super unintuitive since we're already at /dashboard/team!
  return <Link to="./team">A broken link to the Current URL</Link>;
}

We've also introduced an issue that we can no longer move our DashboardTeam component around our route hierarchy easily - since it behaves differently if we're underneath a non-splat route, such as /dashboard/:widget. Now, our "." links will, properly point to ourself inclusive of the dynamic param value so behavior will break from it's corresponding usage in a /dashboard/* route.

Even worse, consider a nested splat route configuration:

<BrowserRouter>
  <Routes>
    <Route path="dashboard">
      <Route path="*" element={<Dashboard />} />
    </Route>
  </Routes>
</BrowserRouter>

Now, a <Link to="."> and a <Link to=".."> inside the Dashboard component go to the same place! That is definitely not correct!

Another common issue arose in Data Routers (and Remix) where any <Form> should post to it's own route action if you the user doesn't specify a form action:

let router = createBrowserRouter({
  path: "/dashboard",
  children: [
    {
      path: "*",
      action: dashboardAction,
      Component() {
        // ❌ This form is broken!  It throws a 405 error when it submits because
        // it tries to submit to /dashboard (without the splat value) and the parent
        // `/dashboard` route doesn't have an action
        return <Form method="post">...</Form>;
      },
    },
  ],
});

This is just a compounded issue from the above because the default location for a Form to submit to is itself (".") - and if we ignore the splat portion, that now resolves to the parent route.

The Solution If you are leveraging this behavior, it's recommended to enable the future flag, move your splat to it's own route, and leverage ../ for any links to "sibling" pages:

<BrowserRouter>
  <Routes>
    <Route path="dashboard">
      <Route index path="*" element={<Dashboard />} />
    </Route>
  </Routes>
</BrowserRouter>

function Dashboard() {
  return (
    <div>
      <h2>Dashboard</h2>
      <nav>
        <Link to="..">Dashboard Home</Link>
        <Link to="../team">Team</Link>
        <Link to="../projects">Projects</Link>
      </nav>

      <Routes>
        <Route path="/" element={<DashboardHome />} />
        <Route path="team" element={<DashboardTeam />} />
        <Route path="projects" element={<DashboardProjects />} />
      </Router>
    </div>
  );
}

This way, . means "the full current pathname for my route" in all cases (including static, dynamic, and splat routes) and .. always means "my parents pathname".

Add experimental support for the View Transitions API via document.startViewTransition to enable CSS animated transitions on SPA navigations in your application. (#10916)

The simplest approach to enabling a View Transition in your React Router app is via the new <Link unstable_viewTransition> prop. This will cause the navigation DOM update to be wrapped in document.startViewTransition which will enable transitions for the DOM update. Without any additional CSS styles, you'll get a basic cross-fade animation for your page.

If you need to apply more fine-grained styles for your animations, you can leverage the unstable_useViewTransitionState hook which will tell you when a transition is in progress and you can use that to apply classes or styles:
```
function ImageLink(to, src, alt) {
  let isTransitioning = unstable_useViewTransitionState(to);
  return (
    <Link to={to} unstable_viewTransition>
      <img
        src={src}
        alt={alt}
        style={{
          viewTransitionName: isTransitioning ? "image-expand" : "",
        }}
      />
    </Link>
  );
}
```
You can also use the <NavLink unstable_viewTransition> shorthand which will manage the hook usage for you and automatically add a transitioning class to the <a> during the transition:
```
a.transitioning img {
  view-transition-name: "image-expand";
}
```
```
<NavLink to={to} unstable_viewTransition>
  <img src={src} alt={alt} />
</NavLink>
```
For an example usage of View Transitions with React Router, check out our fork of the Astro Records demo.

For more information on using the View Transitions API, please refer to the Smooth and simple transitions with the View Transitions API guide from the Google Chrome team.

Please note, that because the ViewTransition API is a DOM API, we now export a specific RouterProvider from react-router-dom with this functionality. If you are importing RouterProvider from react-router, then it will not support view transitions. (#10928

Patch Changes

When submitting a form from a submitter element, prefer the built-in new FormData(form, submitter) instead of the previous manual approach in modern browsers (those that support the new submitter parameter) (#9865, #10627)
- For browsers that don't support it, we continue to just append the submit button's entry to the end, and we also add rudimentary support for type="image" buttons
- If developers want full spec-compliant support for legacy browsers, they can use the formdata-submitter-polyfill
Call window.history.pushState/replaceState before updating React Router state (instead of after) so that window.location matches useLocation during synchronous React 17 rendering (#10448)
- ️ However, generally apps should not be relying on window.location and should always reference useLocation when possible, as window.location will not be in sync 100% of the time (due to popstate events, concurrent mode, etc.)
