broken linebreaks from blogger-beta

Strange, but the bug described in http://vagula.blogspot.com/2006/01/formatting-messages.html that was fixed in January 2006 in Planet OO.o, appears again after switching to blogger beta... Was interpretation fix dependent from site name or smthng like? When yes, maybe should also beta.blogger.com be included into whatever-it-is-or-maybe-not.
