This looks like a bug in the Qt Location Map type. It should be calling 
QQuickItem::setKeepMouseGrab() once a gesture is detected to prevent any input 
event filters defined in parent items (such as the PageStack) from getting 
those events.

Can you create a bug in the Qt bug tracker: http://bugreports.qt-project.org/

Perhaps you are :) The Jolla Sailfish Maps application requires the user to 
switch to split view before moving back through the page stack. This 
essentially bypasses this issue.
