Bug report

Bug description:

In Python 3.12 and below, wrapping a property object with the classmethod decorator would result in a descriptor object that would act like a class-level property.

Here is the code to check this:

class A:
    @classmethod
    @property
    def b(self):
        return 4

print(f"{A.b = }")

On Python 3.12 this prints 4.

On Python 3.13 this currently prints <bound method b of <class '__main__.A'>>.

CPython versions tested on:

3.13

Operating systems tested on:
