set defaultPendingMs to 0 throw an error when root route is not wrapped in suspense

[GuillaumeLaroucheUQAT]

Describe the bug

Setting defaultPendingMs to 0 render the errorComponent if the root route has no pendingComponent or is not wrapped in Suspsense even if a child route has a pendingComponent.

The error message :

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.

This can be temporary fixed by setting defaultPendingMs to 1.
