demo page

platform: iPad(7) iPadOS 16.1(20B79)
magic keyboard hardware version: 0009
magic keyboard firmware version: 0450.0523.0200

can not use magic keyboard trackpad to fast scroll an scrollable container.
step: 
1、open the test html page in safari.
2、use trackpad to click refresh button on link bar;
3、move cursor to the number list container and scroll fast on trackpad.

result: the number list cannot scroll.

weird things:
1、can not make continuous scroll on trackpad,but can sroll slow once by once.
2、after click the page by finger touch,scroll behavior back normal and can scroll fast and continuously。

if you can not reproduce, try a few more times or click to focus the input before scroll.

PS: a bluetooth mouse migth has the same scroll issue,heard from others.

Seems like a dupe of bug 258016

Okay yeah, the attached test case has a `overscroll-behavior-y: none;` property, definitely a dupe. Thank you for the report!
