Describe the bug

Applying the Take kernel to an array of indices and an array of structs I expect nulls in the output in two cases:

  1. If the index is null for the current row
  2. If the struct is null at the index specified in the current row.

Neither of these cases produce a null value.

To Reproduce

See PR.

Expected behavior

See description / PR.
