I don't think the new spec is correct. The question is what happens if
we are tokenizing some foreign content, and we see an HTML start tag.
In the normal case, we pop off all the foreign elements until we get
back to the HTML namespace, then reprocess the token.
In the fragment case, the context element may be a foreign element, so
there was the wrinkle of having to handle that appropriately when we
have this fake "root" <html> element that makes everything confusing.
The new text reads:
"If the parser was originally created for the HTML fragment parsing
algorithm, then act as described in the "any other start tag" entry
below. (fragment case)"
This always just adds the HTML element in place inside the foreign
content, even if the fragment context element *is* a HTML element!
This can't be right, as it means parsing document.body.innerHTML will
behave totally differently to parsing <html><body>, for no reason.
Looking back a couple of years, this section of the spec seems to be
drifting in a random walk away from reality. We can study this further
and try suggesting some text based on what we have implemented so far.
Prince: Print with CSS!
