Range color classes not working

I’m not sure when this stopped working, but you can see it on the Ionic docs too if you use chrome:

Ionic Docs Range

Each of the sliders inside the phone should be a different color.

I’m using Chrome 49.0.2623.112. Also doesn’t work on my phone, Android 6.0.1


I didn’t check on iOS, but on Chrome 50, Firefox 46 and Android 5.1.1 the color has indeed disappeared from ranges.

Hey all, any updates on this?
