Table Of Contents bleeds into the documentation instead of wrapping around

I would assume something with the CSS is broken and is something I ignored assuming it would fix itself but this seems to be an actual problem. I might go in and fix it later after work today, otherwise hopefully someone else will get to it. I used this style of documentation for the [deprecated-params](https://deprecated-params.readthedocs.io/en/latest/) library because the theme was simplistic and readable and had the cleanest format for providing readable code examples.

Feel free to put a simple fix in, but we'll probably be doing some redesign work on this soon anyway. In your particular example, it looks weird to have __init__() listed in the nav menu regardless. I'd suggest reducing the menu depth so that level is not included in the nav.

I think we should be looking into remaking the theme based on Furo rather than alabaster if @Vizonex you'd like to investigate such a possibility.
