Hi Filipe, thanks for the patch.

Usually we don't want to add new, possibly-failing cases to old tests;
that makes it harder to identify when the code regressed vs. when
the test changed to test new things.

It would be better to just copy the framework of tests/shared/051
to a new test in shared/ and test only this new inheritance
problem.

Also, I'm confused about this hunk:

What's that about?

Thanks,
