Throwing a redirect in `beforeLoad` from __root.tsx causes a suspense error

[samchouse]

Describe the bug

If I try to redirect a user in beforeLoad in my __root.tsx file then I get A component suspended while responding to synchronous input. This will cause the UI to be replaced with a loading indicator. To fix, updates that suspend should be wrapped with startTransition. upon visiting a URL that redirects me initially.
