Eager Scale Strategy did not evenly redistribute partitions after a cluster node disconnected and reconnected

Description

After a cluster node is disconnected and reconnected, we have observed that in 8 out of 10 cases, the partitions are not evenly distributed across the nodes.
Testing in a 4 node cluster. Disconnect & reconnect 1 of the 4 nodes.
See the comments below for more detail.
