Hm, looks like `.name` does not exist for `MacOSXOSAScript`:

```

>>> a.name
Traceback (most recent call last):

AttributeError: 'MacOSXOSAScript' object has no attribute 'name'. Did you mean: '_name'?
```

This happens because `MacOSXOSAScript` does not call `super().__init__()` in any way, nor it defines `name` and `basename` attributes.

It has this API for 12 years now: https://github.com/python/cpython/commit/4d39f6e09a5c0a0e09eb51d678bacd1adaa3f2ca

So, I see two possible ways to solve this:
1. Ensure all subtypes of `BaseBrowser` to have `name` and `basename` (because they are defined in `BaseBrowser`) and document them
2. Add a code comment that they are just implementation details and not a part of the public API
