Classification: Plasma
Product: kwin
Version First 6.7.0

DESCRIPTION
I am not sure if this is a Gtk or Kwin issue.
When having a popover tree with two levels, opening and closing the last level
results in the UI no longer receiving clicks. I.e. clicking somewhere like on
the first popover does not close the second popup.
Closing all popups together works, when the last popover stays open. Pressing
ESC always works.
STEPS TO REPRODUCE
Please see the screenshot and the demo application.
