Not really, I just added a note here:

What we currently do is registering sprites (and other characters
that need to be advanced) when the ::stagePlacementCallback method
is invoked.

Last placed character is advanced first.

So that needs to be tested better. We want to include (or maybe 
*only* consider) the HIT character (iff available) when checking
for topmost_mouse_entity from self, while we only want to 
check the others (except HIT) when checking for pointInVisibleShape.
