The RichTextBox method was meant to be a "write-only" value. Bascially meant to be a more "intuitive" way to get RTF formatting without having to specify RTF codes which if memory serves, is a god-awfull thing to even read much less understand.

Shane said "I think Shawn designed it to simply parse out some of the simpler html tags which are then applied using the RTF formatting options.". That's exactly how it works. The "HTML" is lost once applied. Well, not really "lost" but there is no RTF back to HTML logic.
