It's a known issue with the HTML grammar; I've been trying to work  
out in my head how to rearrange the HTML grammars to be less numerous  
etc. Once the best approach is figured out they just need to be re- 
written. In other words it could be fixed, but probably best to put  
the effort toward a new grammar.

There is a grammar that I made as a proof of concept in the  
repository Experimental HTML; but it's highly strict, and only  
supports XHTML 1.0 Strict. On the flipside if your using that it  
works pretty well. :)
