That actually does make some sense if you understand how your coordinates on the map are determined.

Basically, if you're hovering over the zone it's as if you're looking at the normal zone map, but when you mouse off I believe it's zooming out to the continent level.

You'll notice your player coordinates actually change there at the top left from (86.1, 21.6) to (86.6, 21.9).

There are a few potential reasons for this that I can think of:

1. The zone map's position on the continent map is incorrect
2. The zone map's size is incorrect
3. The continent's offsets or size are incorrect

If it helps to understand, this is kind of a rough example of how the zone maps fit together on top of the continent map:


Your coordinates at the zone level are counted from the top left of the zone map and are accurate, but your coordinates at the continent level have to be scaled down and translated over to calculate what your zone coordinates should be since it can only request your position from one map at a time.
