Bichur, you have to open a topic from Discussion in SDC to get the problem (which is still present). When you're using Web Browser, you're really just using IE.
Ah, I see you don't have a Discussion link (on the left pane). That's odd. Maybe something in your settings?
Regarding the differences in your screenshots, I believe IE treats anything in brackets as HTML code, and will simply hide it if it's invalid.
