Sean Quah updated KAFKA-19449:
------------------------------
Description:
We transition to `UNRELEASED_PARTITIONS` when advancing to a new target
assignment and partitions in the assignment are "owned" by another member.
Partitions are considered "owned" by another member if they are in a member's
assignment or partitions pending revocation. Ownership is only updated after
reconciliation has finished.
When the latest target assignment includes partitions from the partitions
pending revocation list, we mistakenly think the partitions are owned by
another member and can transition from `UNREVOKED_PARTITIONS` to
`UNRELEASED_PARTITIONS` instead.
