------------------------------------------------------------
Thanks [~hyukjin.kwon]. From my side, there is no regression. Although I feel
SPARK-34052 is a bit important since it concerns correctness. I'n working on a
fix but got delayed by a few other issues found along the way :(.
The issue has been there for a long time though so I'm fine moving this to the
next release.
