Hi Team,

While going through Blink's commit, I came across another filing testcase:

Test Case - https://jsfiddle.net/dbskt3jo/

^ Try to pick horizontal scrollbar knob and scroll on left side, it will not do anything in Safari 16.2. It works in Chrome Canary 111 and Firefox Nightly 110 and move the scrollbar on drag while selecting knob.

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/platform/Scrollbar.cpp#311

Just wanted to raise so we can fix this bug as well.

Thanks!
