Index out of bounds panic caused by specific combination of window functions

I think this is another form of #16830 which is fixed on main.

Perhaps you can test the latest pre-release version to confirm.

>>> pl.__version__
... df3.filter(pl.col("non_null_count") > 1)

@cmdlineluser I've just tried this on 1.0.0-beta.1 and the issue seems to be resolved. I swear the trace used to end in chunks.rs file so I couldn't find a similar issue. Thanks!
