Looks like flakiness is just on Chrome 77.0.3865 (Windows 10.0.0) FYI.

[dreamofabear]

Do we have a "skip windows" test option?

[Enriqe]

That's true, unfortunately I don't think there is a "skip windows" test option

[dreamofabear]

We can add one. ;)

[estherkim]

Wait no, I removed skipWindows() as a test config because we run almost all Sauce Labs tests on Windows. Skipping should be browser specific at most.

Also I was looking at these tests just now, I'm not sure the OS is the reason for the flakiness.

[estherkim]

:(

[Enriqe]

Alright I reverted the last commit which introduces the skip for windows. Let's just skip them
altogether to unblock master and I'll take a closer look for the root cause.

[dreamofabear]

Good point, what we want is to skip Chrome on Windows specifically. Either way.
