Review comment:
It is. As like
https://github.com/apache/spark/pull/32059#discussion_r608277894, at
`selectField` we treat `GetStructField` and `GetArrayStructFields` differently.
So it causes different behavior in case-sensitive aware resolution here.
It looks like we should better correct them together..
