Difference in documentation popup between Editor and Python Console.

Document popup is different depending on if it is opened in the Editor or in the Python Console. The popup showing in the Python Console is not correct.

For example, `x` is a set and I am trying to see the documentation of the `add` method. Here is the documentation popup of add method inside the editor. This popup contains everything I expect. (I've hit F1 to bring it up)

Here is the documentation popup of the same function inside Python Console. This popup shows an incomplete method signature. This popup does not say that add method needs a mandatory argument.

Why the difference and how can I fix it? It is a bit troubling as I spend considerable time in the Python console.
