SUMMARY With Plasma on Wayland, application windows may not brought to the front when they are called via XDG open - say, when clicking on a link on another application window and that Firefox is behind another window, say a Telegram chat window or Tencent QQ in my case, Firefox shows up with attention highlighting on the taskbar, but was never brought to the front. It does work, however, when I click on a link or xdg-open a link in Konsole. It seems quite similar to this report here on Discuss - https://discuss.kde.org/t/plasma6-windows-are-not-popped-up-activated-on-opened-links/ but I'm not sure if they are related. STEPS TO REPRODUCE 1. Open Firefox or some other default browsers, maximise it. 2. Open a Konsole window, maximise it above Firefox. 3. Open Telegram or Tencent QQ (the only two I have tested, there may be others exhibiting this issue), click on a link in the chat window. OBSERVED RESULT Firefox on the taskbar turns orange (attention), but window remains behind Konsole. EXPECTED RESULT Firefox window should be brought to the front.
