At the end of a drag operation, we would invoke the code to slide the controls in (because we were no longer DND'ing and not hovering) and then immediately afterwards invoke the code to slide it back out when we got the ENTER event from the end of DND. While the immediately overridden tween probably won't have any visible effect it's better to avoid this, so wait to update the zoom state until BEFORE_REDRAW. https://bugzilla.gnome.org/show_bug.cgi?id=640996
