[Bug?] Default Search Form Invalid XHTML

The default search form generated by get_search_form(); is creating invalid XHTML. There needs to be some sort of block-level element between the <form> and <label> tags.

I know that I can override this with searchform.php, the concern is just in the defaults. I’m using version 2.7.1.

(This may have already been reported, but my searches couldn’t find anything.)
