Smart Pinch Zoom issue for map pages fixed

Smart Pinch Zoom is when you start zooming in or out on mobile devices by sliding two fingers towards or away from each other across the screen.

In the past on web pages with maps if one's fingers accidentally went outside the map image then the entire web page changed zoom levels which sometimes led to strange results which unfortunately were not so easy to undo. We have solved this by allowing Smart Pinch Zoom on such web pages only within the map area itself.
