There's also an issue with:

  <!doctype html>
  foo
  <html>

not producing any parse error, because the <html> is the first start
tag token (at least under my interpretation) and therefore is
considered valid. Handling <html> specially in the root element phase
seems like a reasonable way of fixing this.
