ensureSuspendableThenableStateDEV patches then in fulfilled thenables to avoid triggering a custom thenable's then in an unexpected state. However, we weren't doing the same for rejected thenables.

This affected ReactPromise, the type used for thenables passed from server to client. if a ReactPromise passed to use was pending during the render but became rejected between the abort and pushSuspendedCallSiteOnComponentStack, then ReactPromise#then would crash. (see the added test for a reprouction)
This is because we were putting the ReactPromise into an invalid state: a PendingChunk expects to have a value: null | Array<...>, but we were deleting value altogether, and tgus hitting TypeError: can't access property "push" of undefined here:

…Flight chunk that was rejected in the meantime (#36544)
`ensureSuspendableThenableStateDEV` patches `then` in fulfilled
thenables to avoid triggering a custom thenable's `then` in an
unexpected state. However, we weren't doing the same for rejected
thenables.
This affected `ReactPromise`, the type used for thenables passed from
server to client. if a `ReactPromise` passed to `use` was pending during
the render but became rejected between the abort and
`pushSuspendedCallSiteOnComponentStack`, then `ReactPromise#then` would
crash. (see the added test for a reprouction)
This is because we were putting the ReactPromise into an invalid state:
a `PendingChunk` expects to have a `value: null | Array<...>`, but we
were deleting `value` altogether, and tgus hitting `TypeError: can't
access property "push" of undefined` here:
https://github.com/facebook/react/blob/75b0945b18f4a60c80c931fd8067d9c715957879/packages/react-client/src/ReactFlightClient.js#L309

[Fizz] Fix crash when capturing the callsite of a stalled use() of a …
c17dfd8
…Flight chunk that was rejected in the meantime (#36544)
`ensureSuspendableThenableStateDEV` patches `then` in fulfilled
thenables to avoid triggering a custom thenable's `then` in an
unexpected state. However, we weren't doing the same for rejected
thenables.
This affected `ReactPromise`, the type used for thenables passed from
server to client. if a `ReactPromise` passed to `use` was pending during
the render but became rejected between the abort and
`pushSuspendedCallSiteOnComponentStack`, then `ReactPromise#then` would
crash. (see the added test for a reprouction)
This is because we were putting the ReactPromise into an invalid state:
a `PendingChunk` expects to have a `value: null | Array<...>`, but we
were deleting `value` altogether, and tgus hitting `TypeError: can't
access property "push" of undefined` here:

ensureSuspendableThenableStateDEV patches then in fulfilled thenables to avoid triggering a custom thenable's then in an unexpected state. However, we weren't doing the same for rejected thenables.
This affected ReactPromise, the type used for thenables passed from server to client. if a ReactPromise passed to use was pending during the render but became rejected between the abort and pushSuspendedCallSiteOnComponentStack, then ReactPromise#then would crash. (see the added test for a reprouction)

This is because we were putting the ReactPromise into an invalid state: a PendingChunk expects to have a value: null | Array<...>, but we were deleting value altogether, and tgus hitting TypeError: can't access property "push" of undefined here:
