Gallery stops working on mobile devices

[jimihay]

The gallery stops working on mobile devices if you do the following:

1. Setup a gallery with pagination and more than 1 page of images
2. Tap thumbnail to open image
3. Close enlarged image
4. Swipe right to show next page
5. Attempt to tap another thumbnail and nothing happens

The issue seems to be that the event listeners assigned to the viewer are not getting removed when the viewer is closed. Then when attempting to tap on a thumbnail, the viewer event listeners are flipping g_containerViewerDisplayed to true, which in turn is causing the thumbnails' event handlers to return early.

My fix for this is to add the following at line 6874 right above g_viewerSwipe=null;

      if (window.navigator.msPointerEnabled) {
        // Remove Pointer Event Listeners
        document.removeEventListener('MSPointerMove', g_viewerSwipe.handleGestureMove, true);
        document.removeEventListener('MSPointerUp', g_viewerSwipe.handleGestureEnd, true);
      } else {
        // Remove Touch Listeners
        document.removeEventListener('touchmove', g_viewerSwipe.handleGestureMove, true);
        document.removeEventListener('touchend', g_viewerSwipe.handleGestureEnd, true);
        document.removeEventListener('touchcancel', g_viewerSwipe.handleGestureEnd, true);

        // Remove Mouse Listeners
        document.removeEventListener('mousemove', g_viewerSwipe.handleGestureMove, true);
        document.removeEventListener('mouseup', g_viewerSwipe.handleGestureEnd, true);
      }
