Yeah this is something that I was talking about. I only added null checkers so that we don't get in to the state where you have null for the frame. But I don't know (didn't do any research) why is webview crashing.

I've been unable to repro this on macOS; will try on Windows next

I'm going to close this issue as the original reported issue is indeed fixed (ex: no errors showing in the browser console).

I've spent about 20 minutes trying to repro the dead tab issue (which should be logged as a separate issue) on both macOS and Windows and have not been successful
