I don't see how that's relevant. It's what's inside the container that's  
supposed to be WYSIWYG, not the container itself.

Opera places a <br> element in an empty block when you put the caret in  
there, so that's already solved.

The problem I was trying to solve here is *before* you put the caret in  
there. It's hard to click in a zero-height block.
