<option><span><option> doesn't parse correctly

Reviewed by Eric Seidel.

Source/WebCore:

The <option> start tag shouldn't be quite as aggressive in closing open
<option> tags.  I'm not sure whether this was a change in the spec or a
mistranscription, but this patch causes us to match the spec.  I've
checked the other optionTag checks, and they all seem to be correct.
