Some more research. It happens on all zones that appear to be simple
or close to simple rectangles. Whether it shows up or not is merely a
z-order side effect. I do have one zone that is clearly not similar to
a rectangle and it seems to work properly.

On your questions, scaleX,Y are 1, the EventTarget is the MapZone in
question and I am looking at both the localX,Y and the StageX,Y so I
fairly certain they look correct.
