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

**Build scan:**

**Reproduction line:**
```

**Applicable branches:**

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

**Failure excerpt:**
```
java.lang.Exception: Suite timeout exceeded (>= 2400000 msec).
