> Equality comparison for ListArray accounts for offsets incorrectly, so slices of ListArrays with identical offsets but differing values will sometimes compare equal.
> For example, the following test fails:
> {code}
> TEST_F(TestListArray, ValuesEquality) {
>   auto type = list(int32());
>   auto left = ArrayFromJSON(type, "[[1, 2], [3, null], [5], []]");
>   auto right = ArrayFromJSON(type, "[[1, 2], [3, null], [9], []]");
>   AssertArraysEqual(*left->Slice(2), *right->Slice(2));
> }
> {code}
