Autocomplete does not find suggestions in polars namespaces

[kjgoodrick]

Describe the bug

When using polars the marimo autocomplete is unable to find any suggestions for names that are within namespaces. For example, here is what the autocomplete shows for the dt namespace.

Here is what VS Code shows:
