Hover on overload is no longer working

This code here;

```python
class MyNumber:
    def __init__(self, v: int):
        self._value = v

    def __add__(self, v: "MyNumber") -> "MyNumber":
        return MyNumber(self._value + v._value)


# hover on `+` and confirm it shows tooltip for `__add__`
e = MyNumber(0) + MyNumber(1)
```

There is no hover on the "+"
