Deleted this test because it was a duplicate of the one in ReactSuspenseWithNoopRenderer
Builds on behavior added in facebook#23267. Initial hydration should be allowed to suspend in the shell. In practice, this happens because the code for the outer shell hasn't loaded yet. Currently if you try to do this, it errors because it expects there to be a parent Suspense boundary, because without a fallback we can't produce a consistent tree. However, for non-sync updates, we don't need to produce a consistent tree immediately — we can delay the commit until the data resolves. In facebook#23267, I added support for suspending without a parent boundary if the update was wrapped with `startTransition`. Here, I've expanded this to include hydration, too. I wonder if we should expand this even further to include all non-sync/ discrete updates.
Instead of erroring, we can delay the commit. The only time we'll continue to error when there's no parent Suspense boundary is during sync/discrete updates, because those are expected to produce a complete tree synchronously to maintain consistency with external state.

Builds on behavior added in #23267.
Initial hydration should be allowed to suspend in the shell. In practice, this happens because the code for the outer shell hasn't loaded yet.
Currently if you try to do this, it errors because it expects there to be a parent Suspense boundary, because without a fallback we can't produce a consistent tree. However, for non-sync updates, we don't need to produce a consistent tree immediately — we can delay the commit until the data resolves.
In #23267, I added support for suspending without a parent boundary if the update was wrapped with
startTransition. Here, I've expanded this to include hydration, too.I wonder if we should expand this even further to include all non-sync/discrete updates.Updated to include all non-sync/discrete updates.
