Description
Bug Report
Error is not suppressed, since apparently Any isn't considered an instance of DynamicClass/MyClass.
To Reproduce
class MyClass:
...
DynamicClass: type[MyClass]
def foo(self: Any):
super(DynamicClass, self).foo()
Actual Behavior
error: Argument 2 for "super" not an instance of argument 1 [misc]

Research direction
Start by running the provided Python reproduction with mypy 1.0.0 and confirm the [misc] error for super(DynamicClass, self). Trace the type-checking path for super's second argument and add a regression test showing that Any suppresses this instance check; done means the example no longer reports the error.
