No show/map animation on XWayland

[amezin]

After fixing #59 there's now no map/show animation on XWayland - the window just immediately appears. It seems that previously I've been adding it unknowingly, and that caused issues. The animation works as expected in X11 session.

Happens even on v10

I have plans to write an xterm.js-based terminal emulator using GNOME Shell's UI (instead of the current implementation with a separate Gtk application). It should solve all window management issues, like this one.

However, it won't happen soon, as it will likely be a separate project, written (almost) from scratch.

Doesn't happen on GNOME 44, 45 anymore (43 not tested, 42 - still happens)
