@rickhanlonii This test passes but "Foo" is not actually the owner stack trace because the stack starts from where the element was created and that's inside Bar.
This exposes it to captureOwnerStack(). In this case we install it permanently as we only allow one RSC renderer which then supports async contexts. It also exposes it to component stack addendums that React adds to its own console.errors. At least for now.
Since getCurrentStack is now implemented, React appends component stacks to its own logs. However, at the same time we've instrumented the console so we need to strip them back out before sending to the client. This is another reason we shouldn't append them from React.

…ing onError/onPostpone (#30206) Stacked on #30197. This is similar to #30182 and #21610 in Fizz. Track the current owner/stack/task on the task. This tracks it for attribution when serializing child properties. This lets us provide the right owner and createTask when we console.error from inside Flight itself. This also affects the way we print those logs on the client since we need the owner and stack. Now console.errors that originate on the server gets the right stack on the client: <img width="760" alt="Screenshot 2024-07-03 at 6 03 13 PM" src="https://github.com/facebook/react/assets/63648/913300f8-f364-4e66-a19d-362e8d776c64"> Unfortunately, because we don't track the stack we never pop it so it'll keep tracking for serializing sibling properties. We rely on "children" typically being the last property in the common case anyway. However, this can lead to wrong attribution in some cases where the invalid property is a next property (without a wrapping element) and there's a previous element that doesn't. E.g. `<ClientComponent title={<div />} invalid={nonSerializable} />` would use the div as the attribution instead of ClientComponent. I also wrap all of our own console.error, onError and onPostpone in the context of the parent component. It's annoying to have to remember to do this though. We could always wrap the whole rendering in such as context but it would add more overhead since this rarely actually happens. It might make sense to track the whole current task instead to lower the overhead. That's what we do in Fizz. We'd still have to remember to restore the debug task though. I realize now Fizz doesn't do that neither so the debug task isn't wrapping the console.errors that Fizz itself logs. There's something off about that Flight and Fizz implementations don't perfectly align.

Wire up owner stacks in Flight to the shared internals. This exposes it to
captureOwnerStack().In this case we install it permanently as we only allow one RSC renderer which then supports async contexts. Same thing we do for owner.
This also ends up adding it to errors logged by React through
consoleWithStackDev. The plan is to eventually remove that but this is inline with what we do in Fizz and Fiber already.However, at the same time we've instrumented the console so we need to strip them back out before sending to the client. This lets the client control whether to add the stack back in or allowing
console.createTaskto control it.This is another reason we shouldn't append them from React but for now we hack it by removing them after the fact.
