Milo van der Tier 5deb2b4cad LibWeb: Do not give the HTML namespace to elements when parsing XML
While the code that did this referred to the HTML spec, other browsers
appear not to have this behavior when parsing XML, and it breaks a WPT
subtest.

This change does not appear to break any tests, and fixes 1 WPT subtest.
