Can reproduce. Not really a bug, just a weird interaction. I agree we should change it.

Reason is that it's not a "full screen window" in xdg_toplevel terms, but a layer shell anchored on all edges.

We don't want to blindly inhibit as that could affect app launchers. We'll need a new protocol/hint

Yup, I see this in 6.4.4 too. This looks very funny :)
I tried a couple of shortcuts when logout screen is shown as well:
Meta+G for Grid - activated
Meta+C for Cube - activated
Meta+A for for Activities - nope
Meta+V for clipboard history - didn't work but it de-pressed the default "Shutdown" icon for some reason, and I had to hit Esc twice to exist the logout screen (instead of hitting Esc once in other cases)
Meta+L for locking the screen - it worked, and upon unlocking I saw the same logout screen
Meta+D for Show desktop - activated
And Meta+E for Dolphin - it had been launched "behind" the logout screen and stole the focus, so I couldn't use Esc key to exit the logout screen

Something needs to be done with this lol
