This test is still flaky and needs investigation. CI failure: https://app.circleci.com/pipelines/github/MetaMask/metamask-extension/102084/workflows/5eabf94e-d53c-4896-964e-be046bbd4e40/jobs/3802642

Note: I attempted about a hundred times to recreate this particular transient failure (locally, in VMs and in Github Codespaces). I was unsuccessful.

The failure point seemed to be waiting for an alert popup (which already had a 1 second delay before attempting to close it) which, in the CI failure above just shows a spinner at the point the alert should pop up.

27519 adds an additional second to this delay because there does not seem to be another answer.
