[Qt Wayland] `ui_dialogs_in_taskbar__linux` = `false` doesn't work about cudatext HOT 9 OPEN

Bugreport for Lazarus
https://gitlab.com/freepascal.org/lazarus/lazarus/-/issues/40954

from cudatext.

  UiOps.PluginDialogsShowInTaskbar:= cfg.GetValue('ui_dialogs_in_taskbar'+cOptionSystemSuffix, UiOps.PluginDialogsShowInTaskbar);

so, option is applied only to UiOps.PluginDialogsShowInTaskbar which is applied only to PLUGINS dialogs. Cmd Palette is not affected by this flag. it has "never show in taskbar" option. if it shows in taskbar, it seems a Lazarus bug.
I cannot see it on Ubuntu 20 with Gnome, Wayland too, qt5 too.

Find favorite..., dialog from Favorites plugin, is also affected i.e. creates tab in taskbar, acts as a separated window.

Primitive demo for qt5:

tst-ShowInTaskbar-qt5.zip

run 'project1' app.

press button 2-3 times. do all new windows (created by button) have style "show in taskbar"? they have it "NEVER show in taskbar".

from cudatext.

Yes.

Pls show me system info. maybe run 'neofetch'.

This is Wayland-only issue. If I run as xwayland i.e. not true Wayland app, there's no issue.

'neofetch'? what does it show.
