This also reproduces locally for me on master

Found another one in the old CI mails: https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+multijob-unix-compatibility/os=fedora/52/console

@markharwood can you take a look? This looks similar so some earlier cases where the order of xContent deserialization is probably tested the wrong way.

I will not mute this test just yet since it seems to fail fairly rarely so far.

This one failed again in https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+periodic/576/console and reproduces locally also
