Tooltip/watch missing module members

[zooba]

When expanding a module via a tooltip, not all its members are shown.

Even when expanding a module via the Watch window, it shows more members, but not all of them.

dir(sys) has more than either of them. Ideally, all the same members would appear (even __dunder__ and _internal members - debugging is not the time where it's useful to hide information).

This feels like the same issue as #66

[zooba]

Similar, but worse. Most of the missing items do not have underscores at all - they seems to be mostly functions (often builtin functions) or special types. #66 should also be fixed, of course, but this is much more impactful.
