Tiktok.com: Unable to drag volume slider in video's media control.
https://bugs.webkit.org/show_bug.cgi?id=311585
rdar://174179805
Reviewed by Lily Spiniolas.
The problem: iPad converts touches to simulated mouse
events but always sets movementX = 0. TikTok's volume
slider checks Math.abs(e.movementX) > 0 before processing drags,
so all touch drags are silently ignored.
Compute real movementX/movementY in simulated mouse events
by plumbing [previousLocationInView:] through the touch
event pipeline. Enable simulated mouse event dispatch for
TikTok and Facebook, scoped to elements with role="slider",
and prevent background scrolling during slider drags.
