Hmm, cannot reproduce with those steps.
neon unstable updated to Firefox 115 before I reported this bug. But it's RC1, not final 115 version, then I think the issue could be a Firefox bug.
Aha, could be. I'm using Firefox 114 and I can't reproduce it with that. Can you report it at https://bugzilla.mozilla.org?
There is something wrong on neon unstable. I can't reproduce with the same version of Firefox (115.0.1) on Arch Linux.
Can reproduce on Wayland, cannot on X11. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.81.0 KDE Frameworks Version: 5.245.0 Qt Version: 6.6.0 Graphics Platform: X11
