Why doesn't mypy understand my simple class decorator?

My problem can be explained with this simple example:

from typing import Any, Type

class CallMe:
    def __init__(self, *args: Any, **kwargs: Any) -> None:
        pass

def callme_factory(c) -> Type[CallMe]:
    return CallMe

@callme_factory
class DoNotCall:
    pass

print(CallMe(1,2,3))
print(DoNotCall(1,2,3))

It runs and outputs two CallMe objects:

<__main__.CallMe object at 0x0000017E6C5EF280>
<__main__.CallMe object at 0x0000017E6C5EF280>

But when I run mypy for it, it raises an error:

test_mypy.py:15: error: Too many arguments for "DoNotCall"
Found 1 error in 1 file (checked 1 source file)

That happens even though I annotate that callme_factory() returns a subclass of the CallMe class.

My question is:

1. Why does mypy miss this?

2. How do I get it to read the code correctly?
