This filter resolves the described bug, but not all cases described in the trac ticket above.

add_filter('the_content', function($content) {
  return preg_replace("/(<\/\w+>)\&\#8222;(\S)/u", "$1“$2", $content);
});

thanks for the link!

I think some regex filter added to the_content might also work, as long this bug is not fixed upstream.

thanks, that resolves the issue.
