in this example map element stretched in full screen, we have 2 translucent blocks 'citylist' and 'menu' which overlap each other. Each unit has a hover, which changes background color to red when 'clicked'. The example shows that if the "click" on the intersection of two blocks change the background does not happen, although is crossing works. If you remove the library from Google Maps, it all works. Tested on several desktop browsers, and several phones. This problem is present only in the mobile browser version.
