There was a problem hiding this comment.
I think we should be more explicit about when we are in a stalled retry render rather than inferring too much. I wonder if multiple aborts could lead to this getting through here in dev when it wouldn't otherwise. You could make a new dev only status for the task that is checked instead

Same as #33634 but for
useand promise-as-a-child.An alternative to re-rendering would've been to eagerly collect
use()calls but we knowError()is slow in v8.The danger with lazily collecting
use()is that the Thenable may be resolved when we abort.In those cases we remove instrumentation on the last thenable to ensure we suspend again. To ensure Thenable subclasses can't observe the corrupted state, we noop
.then.The shown stack relies on sourcemaps with
ignoreList. Otherwise it'll point into React internals. From the dispatcher we wouldn't know how many stacks we have to cut without a circular dependency to theReact.usefunction.
