SUMMARY With click to cycle windows enabled, in wayland if you click on a group of window icons in the taskbar to cycle through them, it does not cycle them and doesn't do anything for that matter. Observed on Arch Linux and KDE Neon User Stable in Wayland. OBSERVED RESULT Nothing happens. EXPECTED RESULT Clicking grouped icons only task should cycle the windows and cycle through them as if you did a alt-tab.

I've discovered the cause for this bug. It's the Xwayland window focus bug causing this to happen. When an XWayland application such as spotify is in focus and you try to focus say firefox wayland, it will not pop over the spotify window.
