The list of flakes gives only 5 instances of the flake over the last week; the flakiness dashboard is mostly green. I'm not disabling the test at this stage, but this decision should be revisited if it starts flaking more.

The logs say

Assigning to ekaramad as the author of this test, taking a guess at component, and removing Sheriff-Chromium label.
