HTML5 parsing requirements will fix this both for <legend> and for  
unknown elements.

For what it's worth, all non-IE browsers handle unknown elements in a  
consistent way, and IE can be made to do so by first creating an  
instance of said element in script. <legend> is not a new element  
though, it has a longstanding use in <fieldset> many of it's  
particular oddities stem from the fact that browsers have only  
expected it to appear inside <fieldset>, where it has specialized  
rendering.
