REGRESSION(305618@main): [iOS] Swipe gesture fails to reliably trigger scroll
over certain HTML content in Mail
https://bugs.webkit.org/show_bug.cgi?id=306977
rdar://169511014
Reviewed by Simon Fraser.
Our adoption of `setDecelerationTrackingBehavior` broke scrolling during
an existing momentum phase on certain HTML content in Mail.app.
This commit is a simple revert of 305618@main, unfortunately bringing
back webkit.org/b/302754.
