Problem verified on iPhone, iPad, and Samsung Nexus (Android) mobile browsers
Problem does not happen on Desktop Chrome though (as I believe google autoloads modified api for mobile devices)
Map renders and works fine apart from Google Maps controls (e.g. Map/Satellite) for example are not responding on the click event -> map types not switching in that case. On iPhone nothing happens, on Android, they briefly highlight, but still dont respond properly.
Seems like the touch event somehow get filtered/interfered with.
This also happens on google maps embedded manually on a Ext.Panel.
