fix(wm): handle hide events for layered windows

This commit ensures that Hide events on Layered windows (usually added
when the transparency feature is enabled) will always be considered
eligible for handling.

This will avoid situations where ghost borders are left behind because
the Hide event was ignored.

fix #878
