Subject: Markdown importer: keep entities in HTML blocks with the HTML

If an entity occurs directly in markdown, we parse and insert it
directly; but if it occurs in an HTML block, it has to be added to the
HTML accumulator string for deferred parsing when the HTML block ends.

Pick-to: 6.2
Fixes: QTBUG-91222
Fixes: QTBUG-94245
