Thunderbird - Wayland / other apps

[lejeczek]

Hi guys.

I think it came with an update a few releases ago - 
Thunderbird no longer stays on the monitor it was on, prior 
to screen-saver.
After screen-saver was invoked, Thunderbird goes onto the 
main monitor always - for those of us who have two-monitor 
setup, needless to say.
I wonder if Fedorians see this - Thunderbird & Firefox 
(multiple windows/instances) not remembering it's monitor 
position, has been an on-off issue for a last few yeas - 
with other apps too?

Perhaps answers here, could be useful feedback for devel - 
as to whether it's Gnome/Wayland & all-apps or/and only 
given apps(their issue).

thanks, L.
