    Is that really fixed? I get crashes (or calls of wrong methods) in 2021.3.19f

    This is still reproducible on Apple silicon mac.
    - 2021.2.19f1 (silicon build)
    - 2021.2.17f1 (intel build)

    It only happens when number of generic arguments of parent interface is less than implementing child interface.
