The flakiness initially reported in the ticket, has been fixed in the PR #27684.

But when this PR #28153 was unable to be merged, a discussion took place in the slack channel and this flaky test appeared with another reason details in the CI link.

According to the log, the failure occurs in the Chrome browser when the delay await driver.delayFirefox(1000); is executed, which should not have been executed. Hence further analysis of the flaky test needs to be done.
