Summary:
Currently, every warning triggers a packager request to symbolicate the stack trace. If there happens to be a lot of warnings or if the packager or device are pretty busy (or low powered), this can cause a significant delay in responsiveness (and development velocity).
This fixes the issue by only symbolicating warnings when users inspect them.
