There was a problem hiding this comment.
pendingUnmountedRootID was never actually written to. The root was just unmounted by virtue of being included in the normal unmount operation. There wasn't anything special to be done with the root until now.
A single unmounted root ID is sound since we always flush operations after unmounting a component.

Mostly so that we don't trigger unnecessary warnings in older React versions.
We could avoid the additional capability in favor checking if the root exists in the Suspense tree but that may hide legit bugs.
