Subject: [PATCH] Mobile webclient: Try to fix issue where webclient would end
 up stuck as unfocused, and pressing 'Back to Game' did nothing (e.g. after
 clicking OK to the 'ran out of memory' dialog in chrome on android)

You can still force focus to be regained by switching to another tab or triggering the on-screen keyboard somehow by e.g. trying to change an option - although that was pretty unintuitive
