I've noticed when replying to Outlook html-formatted messages that:
1) they often contain inline css stylesheets
2) the style tags are stripped out in the reply (when tinymce serializes its html), but the inline css rules code remains. I guess this has something to do with avoiding xss attacks? or just to prevent css rule name clashes?
3) despite the css rules within being "hidden" in an HTML comment (MS actually attempting to play nice!), the comment is neutered by tinymce and all the rules display in my reply.
The end result is that the reply contains (A) my msg, then (B) "xxx wrote..." then (C) a bunch of css garbage shows up as msg text before (D) the original quoted email.
