Polars `pl.Expr.filter` function signature not accurate

[henryharbeck]

Describe the bug

Type pl.col("").filter() in a marimo cell and hover over the filter method.

Note that the displayed function signature is missing the *predicates parameter

*predicates can be seen in the parameters section and here in the Polars docs

As seen in the "environment" section, I am on the current version of Polars.

@henryharbeck, could you please file this in the Polars repo? I think this is a bug in Polars and Jedi playing together. (similar to https://github.com/pola-rs/polars/issues/16933)

Thanks @mscolnick, that makes sense - my apologies.

Have raised the issue linked above

I took a look; doesn't seem to be a Polars issue (and is definitely unrelated to the previous autocomplete fix/enhancement), so I have closed the issue on our side.

The Marimo/Jedi stack seems to be experiencing a specific edge-case related to the first parameter name - if I do nothing but locally rename it to seemingly anything other than *predicates then everything works as expected 🤔

It looks likes its coming from Jedi then, but I cannot re-produce it outside of polars:
