Particularly important was _XWAYLAND_ALLOW_COMMITS atom which caused
some annoying flicker when resizing or hoovering over buttons.
This was introduced with 'shared/xcb-xwayland: Split into common
helpers' and somehow I missed those atoms.

https://specifications.freedesktop.org/wm-spec/1.4/ar01s05.html says
"The Window Manager MUST set _NET_FRAME_EXTENTS to the extents of the
window's frame", so this is probably something we should be doing.
Some programs (such as some versions of Firefox) expect this to be present,
and will render popups in wrong locations if it's not.
