Engage in iframe on iPad

Hi,

When I load a presentation (Engage '13, published to the web, with html5, no app) in an iframe in Safari on an iPad what happens is that an initial "play" button shows up. Once I tap the iframe (it doesn't matter if I tap the button or anywhere on the iframe) the presentation loads successfully.

I know on iPads a touch is required to play music but other than that is there any reason why you have that play button? Can I remove it? 

The issue is that for some reason on the iPad a black rectangle is displayed for the iframe until you tap the button. After that it disappears and the player loads nicely. I need to get rid of the initial black rectangle.

Any suggestions would be appreciated!

Thanks,

Zsolt
