Sure, but this behavior actually makes sense to me. It's just an error  
handling rule for when the value is not the empty string (to allow  
<div contenteditable>, true, or false)... In other words, it makes:

   <div contenteditable><p></div>

... equivalent to:

   <div contenteditable><p contenteditable=x-test></div>

... which doesn't seem that bad. This doesn't change how  
contentEditable, isContentEditable or anything would work.
