At present, if <allowoverlay> is set to yes then overlays are disabled when a menu panel is accessed i.e. facade is not in focus.
I do not know if there is a good reason for this, but I doubt it since you can define overlays that work perfectly even when the facade is not in focus.
Many skins are now using sliding panels more often. Skins seem to be developing their own overlays more often and turning off allowoverlay, and I would guess this is mainly because of this limitation. A lot of time could be saved by enabling overlays when the facade is not in focus.
