I might be mistaken but shouldn't the rejection.stack unwinding be done optimally before the final JSON.stringify((rejection: $FlowFixMe))?

No, I don't think so, stringify does not unwind the stack or show it in the logbox . The stringify call is only for extracting a message.

…info if possible (#42079) Summary: This is a continuation of my [last PR](#40914) which improved the symbolication of unhandled promise rejections. While I was developing another library I noticed I still got an error stack of the log adding and not of the error itself. The library I'm trying to debug does not throw a standard error object but rather a custom one, but it still contains the stack field. By passing this stack field to the logbox call I was able to get a better symbolicated stack trace. The exact line of the failure is not displayed but at least the correct file is. ## Changelog: <!-- Help reviewers and the release process by writing your own changelog entry.
