           Summary: <basefont> should not break out of 'in head', should
                    be treated as a void element within <head>
           Product: HTML WG
           Version: unspecified

               URL: https://bugzilla.mozilla.org/show_bug.cgi?id=571389
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: HTML5 spec (editor: Ian Hickson)
        AssignedTo: ian@hixie.ch

It appears that the banking site TD Canada Trust uses the <basefont> element
followed by the <base> element. Per the HTML5 parsing algorithm, <basefont>
breaks out of "in head", so <base> gets appended to <body>, where it no longer
establishes the base URL per
http://www.whatwg.org/specs/web-apps/current-work/#document-base-url . This
breaks relative references on the site.

The appropriate fix would be making <basefont> in 'in head' insert an element
for the token, immediately pop it, acknowledge the self-closing flag but not
change the insertion mode.
