I would consider that as a bug. Note that PHP Markdown Extra's HTML  
parser handle this quite well, but this has a cost in complexity and  
speed.

I don't think this can be handled correctly in the general case,  
although it certainly could be handled more elegantly for a vast the  
majority of times by considering the paragraph closes at the first  
blank line. I'm not sure it's worth adding a special case for it  
however.

This last one works fine in PHP Markdown since 1.0.1d. Perhaps you  
could adapt PHP Markdown's balanced HTML parser.

That's not even valid HTML... It works fine when I change the third  
`<div>` for a closing tag however.
