Intermittent test failure in CI

The following test may be failing intermittently in CI (see [failure](https://app.circleci.com/pipelines/github/influxdata/influxdb/44766/workflows/97f745cc-0b15-4aac-b76f-59d71ebb28b0/jobs/423691)): https://github.com/influxdata/influxdb/blob/ba7e6c6986a910c9d0b32982d19da60a8aeb0d0b/influxdb3_write/src/write_buffer/mod.rs#L2452-L2453

Opening this issue to track and follow up if/when necessary.

Start with the referenced lines in influxdb3_write/src/write_buffer/mod.rs and inspect the linked CircleCI failure. Determine why the test can fail intermittently in CI and document or implement a reliable resolution, with the test passing consistently in CI as the completion criterion.
