Thanks for testing. Zoom out should work the same way as in Map
Display. Could it be caused by the different extent? Also the question
is when you are comparing two maps with different extent should there
be some warning? Because it could confuse the user. On the other hand,
different extent of maps in Map Swipe is completely valid if you are
aware of it. For me it works ok.
