I'm unable to reproduce this now, I wonder if it got fixed by this:
https://github.com/microsoft/vscode/pull/248565/files which was trying to find a next focus item and fail.

@roblourens Are you able to reproduce this still?

Seems like it's working now

I was getting this again today, same error and repro steps
