Review Comment:
@snuyanzin I believe the key point here is that the changes that fix the
issue for 2.0 have a much broader scope and it has been agreed that we will not
backport features from 2.x into 1.x line (as discussed
[here](https://github.com/apache/flink/pull/25656#discussion_r1852573652)),
hence a more narrow fix is required.
