When a component suspends with `use`, we switch to the "re-render" dispatcher during the subsequent render attempt, so that we can reuse the work from the initial attempt. However, once we run out of hooks from the previous attempt, we should switch back to the regular "update" dispatcher. This is conceptually the same fix as the one introduced in https://github.com/facebook/react/pull/26232. That fix only accounted for initial mount, but the useTransition regression test added in f82973302b3f490ec120c3b102e8c3792452dfc9 illustrates that we need to handle updates, too. The issue affects more than just useTransition but because most of the behavior between the "re-render" and "update" dispatchers is the same it's hard to contrive other scenarios in a test, which is probably why it took so long for someone to notice.
