Sql consistency when partition evicts.

Hi!
I found recently quite surprising on the first sight behaviour.

Scenario:
1. Start 2 node with indexed atomic partitioned cache with 0 backups.
2. Load sufficient amout of data (or emulate slow removal from idx)
4. Start another node.
4. Perform SELECT * FROM <TABLE>.

Due to partition eviction, number of returned rows from SQL are
sufficiently bigger than
expected. Reproducer is attached to jira issue [1]

Is this known issue? Is it expected behaviour due to our SQL indices design?
