nba.com: Unable to scrub volume slider using gaze and pinch [visionOS] and
touch [iPadOS]

rdar://147428926
Reviewed by Aditya Keerthi.
The problem was that when the user touches a <input type="range">,
the touch had to land precisely on the thumb point of the slider
for it to work (very hard to achieve).
The fix matches UIKit's UISlider behaviour,
it expands the thumb's touch hit area by 12.5pt if the
thumb is smaller than 48pt in either dimension.
Test generated with assistance from Claude.
