Just got a bunch of instances of this suite timing out all on Windows agents. Could be a coincidence but seems unlikely.

**Build scan:**
https://gradle-enterprise.elastic.co/s/rvfpi7upehqjk/tests/:x-pack:plugin:esql:test/org.elasticsearch.xpack.esql.expression.function.scalar.nulls.CoalesceTests
**Reproduction line:**
```
null
```

**Applicable branches:**
main

**Reproduces locally?:**
Didn't try

**Failure history:**
https://gradle-enterprise.elastic.co/scans/tests?tests.container=org.elasticsearch.xpack.esql.expression.function.scalar.nulls.CoalesceTests&tests.test=classMethod
**Failure excerpt:**
```
java.lang.Exception: Suite timeout exceeded (>= 2400000 msec).
