This is another side effect of processing annotations (at the symbol table construction stage) (and I would assume there are a few more cases like this);

def foo():
    outer_var = 1

    def bar():
        inner_var: outer_var = T
    
    return bar

inner = foo()
print(inner.__closure__)

In theory, there shouldn't be any cells / references to the variables from outer scope, but since we process the entry for the annotation and record `outer_var` as a free var it is listed here.
