Environment

[skip envinfo]
I'm running on iPhone SE, iOS 11.4, RN version 0.57.

Description

If you tap the circle of a slider, you'll see it jump. It seems like the slider might not be calculating the delta between the touch's position and the position of the circle at the start of the drag. It's a lot more noticeable in the simulator than on device.
