https://patch-diff.githubusercontent.com/raw/saltstack/salt/pull/40159.patch
https://patch-diff.githubusercontent.com/raw/saltstack/salt/pull/40206.patch
The behaviour though was back off by default in a later commit again
cf. https://github.com/saltstack/salt/pull/40206
The fix is the second part of the #40159 PR, but the behaviour is turned
off by default and needs considerations of admins before enabling. We still
consider the issue as fixed starting with this change. Details in
