Checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of Polars.

Reproducible example

import polars as pl

df = pl.DataFrame({
    "a": [1, 2, 2, 3, 3],
    "b": [2, 2, 4, 7, 8]
})

df.with_columns(
    pl.col("b").implode().over("a", mapping_strategy="join")
      .list.set_intersection([1])
)

# PanicException: assertion `left == right` failed
# left: LargeList(Field { name: "item", data_type: Int64, is_nullable: true, metadata: {} })
# right: Int64

Log output

thread 'polars-3' panicked at crates/polars-ops/src/chunked_array/list/sets.rs:367:5:
assertion `left == right` failed
  left: LargeList(Field { name: "item", data_type: Int64, is_nullable: true, metadata: {} })
 right: Int64

Issue description

Just while experimenting with the repro in #17129 I stumbled upon this panic.

I think it may be a slightly different issue as this also panics in 0.20.31

Expected behavior

Appropriate error instead of panic.

Hello,
This seems to be related to the double list generated by implode() which has been reported but seems to be intended (Cf. #10042)

If we flatten the result it works in 0.20.31, but fails as in #17129 in 1.0.0b1 :

df = pl.DataFrame({"a": [1, 2, 2, 3, 3], "b": [2, 2, 4, 7, 8]})
(df.with_columns(pl.col("b")
   .implode().over("a", mapping_strategy = 'join')
   .flatten().list.set_intersection([4, 8]))
)
