"@classmethod" decorator suppresses class variables

[jhenhapl]

Environment data

• Language Server version: Pylance language server 2021.3.0
• OS and version: Windows 10
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.7.2

Expected behaviour

It works as expected without the @classmethod decorator.

Actual behaviour

After adding the decorator, the class variable is unrecognized even though calling Test.test() still returns 1.

Code Snippet / Additional information

class Test:
    var = 1

    @classmethod
    def test(cls):
        return cls.var

print(Test.test()) # prints 1
