After some time, copy'n'pasting text (be it from the URL bar or from some website content) from Firefox to some other application stops working on my Wayland session.
Steps to reproduce:
- log in to a Wayland session with KDE Plasma
- start Firefox
- test that you can copy'n'paste text from the Firefox URL bar and from websites to other applications (e.g., Kate as a text editor)
- work for a few hours
- test again that you can copy'n'paste text from the Firefox URL bar and from websites to other applications (e.g., Kate as a text editor)
The copied text from the URL bar and the websites can be pasted to Kate.
Nothing is pasted to Kate (not even the text that was in the clipboard before).
I have no idea what exact time needs to pass before this problem occurs, or whether some specific action triggers this problem. I first though that hibernation/standby triggers this, but it doesn't.
Copy'n'pasting within Firefox and from Kate to Firefox keeps working.
After restarting Firefox, copy'n'pasting will work again for some time.
I have not tested whether this problem occurs with an X11 session as well.
This is with Firefox 98.0.2 from Kubuntu 21.10 in the DEB version (not the Snap version).on KDE Plasma 5.24.4 with KDE frameworks 5.92.0 and Qt 5.15.2.
