I closed the backport PR as the fix for bug 1921335 includes a regression: https://github.com/thanos-io/thanos/issues/3990. The resolution of this bug depends on bug 1955586, so we can't make any progress on it until it is resolved. Test with payload 4.8.0-0.nightly-2021-07-29-033031, alert rule changed and query data make sense.
