Commit b1a0bf891 broke the previous logic that we would only fallback to the root cursor if 1) windows are not interactable or 2) no window cursor is currently set (i.e. not hovering over any window). Now it will set up the root cursor if it's NULL, which breaks clients explicitly setting an invisible cursor. This commit restaurates the previous behavior. https://bugzilla.gnome.org/show_bug.cgi?id=754806
