Whether it is a bug or not can be best clarified by looking at the
documentation: If it is documented that attributes of super objects
always follow MRO, then there is a bug. That might be a doc bug, but

Special cases aren't special enough to break the rules.

makes clear it wouldn't be a doc bug, but a bug in the code.

OTOH, if this is not documented at all, you clearly have a doc bug.
