Outlook conditional formatting doesn't match text in links

I'm trying to highlight mails that contain my name inside the message. If I perform a search with about:Fabian everything works as expected and Outlook finds all mails.

However if I set up a conditional formatting rule with Search for "Fabian" in field "subject" and message body, only some of the messages are highlighted.

To be more precise: Apparently it only matches if my name occurs as plain text. As soon as it is in a special format (e.g. strikethrough or in the text of an HTML link), the rule doesn't match anymore.

Is there any way to get the conditional formatting the match also HTML text and to behave like the normal search?
