The test did not get muted and did not fail in the last 17 days, plus it's not reproducible locally. I am going to close this for now.

A similar failure happened - https://gradle-enterprise.elastic.co/s/jlasxj7sgru44/console-log?anchor=20165&page=21. Doesn't reproduce locally, but looks like it may be an intermittent issue?

Relabelling this as well because from the assertion that fails, this does not seem to be a search problem.
