This test keeps failing and looks flaky. Skipping for now.

master/8.0: 21820e9

The test setup is against an instance of Kibana on 8.0.0 that was previously migrated to 8.0.0 using the v1 migration algorithm.
In this case, the v2 migration flow converts .kibana_1 to .kibana_8.0.0_001, copying all documents over to the new alias.

I created a new fixture using the default distribution with the flights sample data. PR #102139 passed 100/100 times on the flaky test runner. See PR for details.
