It seems like a RippleDrawable bug on lower APIs, with which there's not much we can do.

We can probably expose forceDrawCompatHalo so the client can opt to use a compat halo instead on those lower APIs. But it may not be a good idea to use it by default.

I don't know... a ripple in Seekbar on API 27 seems to work properly, mb Slider can be fixed too?
