Try saving a RTFD TextEdit document (add an attachment to a rtf file), you should have the same problem as OO and OG. Yes, Pages and Keynote can do it correctly, and that's because Apple specifically fixed them instead of doing a global fix. We may end up finding a fix for it ourselves but we can't make any guarantees when that will be. We know this causes a lot of grief for some of our users and we apologize for that.
