Comment(by coffee2code):

 I wanted to err on the side of thoroughness.  I don't believe it's the
 function's purpose to be aware of context or anything DTD-related except
 for tags that are allowed to be self-closing.  If implemented as per the
 patch, someone could conceivable use it to properly tag-balance HTML
 intended to be output in the HEAD.

 Encountering a HEAD element in the BODY is already invalid in and of
 itself, so tag-balancing those misplaced tags is at least one step in the
 direction of properness.  At the very least it does no additional harm,
 but allows the function to be used for HTML intended for the HEAD.
