I can't make an item frame (empty, or containing an item) catch on fire. Obviously tapping it with flint and steel puts the flint and steel in the frame or rotates the item already in the frame, but lighting things on fire around the item frame does not cause the item frame to eventually catch fire too. Seems to me like item frames transitioning to block entities need to have some flammable attribute set.

Note, I've presumed that item frames should be flammable...
