Review comment:
       Thank you for the review! I executed mentioned test case multiple times with reverted changes and test case failed every time. It was always the case that first five Oplogs were not compacted as expected. It is possible that this test case is flaky in some way, but I cannot reproduce it or see anything suspicious. Could you please send me logs from test case execution where it pass after you revert the changes?
