Why disable the test instead of reverting the culprit cl?

The CL fix will land today. 

Assign to fsamuel@ to land the fix and revert #17. Or you probably should land your fix and reenable the test in the same CL.

Removing Sheriff-Chromium as the test is now disabled.

I was able to reproduce the error locally on a Windows device.
