Backport PR #7106: Changed the display order of rich output in nbconvert html The notebook rich output display order now matches that of nbconvert. This makes more sense than the other way around due to the need for the that are notebooks already shared on the web to remain consistent. Conversely local notebooks can simply be edited to match the new order.
