SUMMARY

If I have an XWayland window of a KDE application focused, and perform the "Switch between windows of current application" action (Alt+` by default), only other XWayland windows of the same application are displayed in the selection list, but not Wayland windows of the same application.

STEPS TO REPRODUCE

1. Open two copies of KWrite, forcing one of them to run under XWayland, for example, like this: `WAYLAND_DISPLAY= kwrite`
2. Focus the XWayland copy of KWrite
3. Perform the "Switch between windows of current application" action (Alt+` by default)

OBSERVED RESULT

Only the current window (running under XWayland) is displayed in the selection list

EXPECTED RESULT

Both windows, one running under Wayland and one running under XWayland, should be displayed in the selection list
