bug#60356: 30.0.50; individual frame loses keyboard focus, focus cannot be restored

[git@sphalerite.org]

The exact action leading to this bug is not clear to me. It seems to be
related to lsp-mode though -- I've not observed it happening without
lsp-mode.

The symptom is that a single frame will no longer accept keyboard input,
and will visually indicate that it is not focused (outline rectangular
cursor where I'd usually expect a solid rectangular cursor). Mouse input
still works, and other frames still accept keyboard input as normal.

I'd be glad if anyone could point out ways to further debug this issue.
I'm also in #emacs:matrix.org (@linus:schreibt.jetzt) in case
fast-turnaround communication would be helpful :)
