FYI, not to be too 'lawyerly' about this, but someone else had already expressed interest in working on this task in the issue i opened (which is now assigned to them), so it would seem polite IMO to see if they are still interested in taking it on before progressing this. cc @robpatterson13. obviously still great to have people picking things up though!

Hey no problem, I saw now that @robpatterson13 just got assigned, @robpattterson13 feel free to take over this pr if desire to work on this.

The PR needs to have all of the existing test-cases updated to check for the new fix-it just like #85830 does for await. Please coordinate in the issue re: who is going to work on this since there are multiple people interested.
