Subject: QTextHtmlImporter: don't forget to appendBlock after block tag closed

If we see a closing tag that really demands a new block after it,
like </ul>, that needs to be done even if some ignorable whitespace
and "inline" tags come after it. Don't get distracted by those.

Also add a comment in QTextDocument::setHtml() to remind the reader that
HTML parsing is a two-pass algorithm.

Fixes: QTBUG-81662
