Comment:

 @swissspidy @westonruter would appreciate some review on this. It seems
 ready to go, but should be ported into the 6.5 branch. Should I go ahead
 and merge it into `trunk`?

 The quickest context is that we initially thought that we could overlook
 text nodes in the HTML Processor (vs. the Tag Processor) because 6.5
 wasn't going to support visiting them in that class. However, those text
 nodes can trigger a process called active format reconstruction which can
 change the stack of open elements. Thus, we're in a bind and //have// to
 support text nodes regardless.

 It's thankfully a small patch, and technically removes an oddity of the
 Tag vs. HTML Processor interfaces in the process, because with this patch
 both can now visit all tokens in a document.
