Reproducible Failure in org.elasticsearch.search.aggregations.bucket.TermsDocCountErrorIT.testIncrementalReduction

[original-brownbear]

With current master:

./gradlew ':server:internalClusterTest' --tests "org.elasticsearch.search.aggregations.bucket.TermsDocCountErrorIT.testIncrementalReduction" -Dtests.seed=370A19D46176CFA7 -Dtests.locale=zh-SG -Dtests.timezone=Atlantic/Madeira -Druntime.java=16

fails 100% of the time with

for me. Also fails for a bunch of other seeds as well.
