Incorrect draggedTrackPos X coordinate value during DnD Track

[RomanSuvorov]

When drag track to the new position, draggedTrackPos X should be set like start of rect this.trackRef.current, not a clientX. This produces bug, when track goes faster, than mouse this do.

react-range/src/Range.tsx

Line 476 in 2a634cd

draggedTrackPos: [clientX, clientY]
