Thanks for the feedback, that's strange about insert+space in NVDA, which 
version are you running? The new release of NVDA came out a couple of weeks 
ago, and is 2014.1.

I understand your point about the WhatSock sample not announcing the content 
when focus moves within, however there is no role=dialog, so you can use 
Browse Mode to arrow down the page, and the background content is hidden via 
aria-hidden=true, so you will never encounter the obscured content on the 

Is Browse Mode not activating? Is this in Firefox?
