I know this is a very niche kind of concern, but I did a bug report for it on GitHUb which was closed without seemingly much consideration.
Here’s the report in GitHub:
So what happens is that this keyboard shortcut that usually switches focus to the Finder for some reason doesn’t do that when the Bitwarden desktop app vault is locked, but it does when the vault is unlocked.
I wonder why as I haven’t seen that happen in any other app,
It’s a small thing, but still breaks something that’s consistent elsewhere.
It seems like the bug report was closed because Bitwarden staff were not able to reproduce the problem.
Perhaps if other users experience the same problem and describe their setup by posting here, it will be possible to determine under what conditions this issue may occur. Returning to GitHub with more information about how to reproduce the observed behavior may convince them to re-open your issue.
