HTML tabs break in new discussions

Community Explorer

Oh! I'm excited about many of the updates to the discussion tool. However, it appears I am unable to use TABS in the new tool. Is this by design? An oversight? 

I am an instructor and unfortunately, I spent all last semester updating my discussion assignments to include TABS. Please tell me I'm missing something...

Just to check, I toggled between New Discussions and the old (with no other changes). the tabs showed up fine with old discussions...and broke with new.

My fingers are crossed...thank you!
