Parking this in blocked until T439780: Catalyst the first edit using each tag is saved without its tag is resolved. This test is currently running daily, but the first run will fail each time, and then it will pass on retry. See linked ticket for more details.

This appears to be raising a valid issue, so probably it needs fixing as opposed to disabling the behaviour that causes the issue? I would have thought MediaWiki should support innodb_snapshot_isolation being enabled (even if production does not / will not do this)

@Dreamy_Jazz what version of mariaDB are you on in your local? See this potentially related ticket, T439780.

One additional note, this is an issue only in Catalyst now because it is the only (as far as I can see?) env running 11.6.2 or later, which is when this behavior became default. The catalyst env I tested this on was on 11.8.2-MariaDB. BUT, as we upgrade jenkins, betacluster, and prod to anything 11.6.2 or later then this will likely also present in those envs.
