Turning on designMode from within $(document).ready() broken

[sebwin]

Applies to Gecko browsers. (at least Safari works fine)

Usage:

$(document).ready(function(){
  document.designMode = 'on';
});

When applied to the _top document this causes a mozilla browser to display a blank page.
When applied to an iFrame it has no effect whatsoever.

That's correct - you can't turn on the designMode of the document that you're in. There's really nothing that we can do in this case.
