"Non-native" scrolling animations are disabled for iOS even when the RenderLayer specifies that the ScrollAnimator should be used. This is currently implemented via an #ifdef [1]
#if ENABLE(SMOOTH_SCROLLING) && !PLATFORM(IOS_FAMILY)
if (m_scrollableArea.scrollAnimatorEnabled() && !behavior.contains(ScrollBehavior::NeverAnimate)) {
m_scrollAnimation->setCurrentPosition(m_currentPosition);
return m_scrollAnimation->scroll(orientation, granularity, step, multiplier);
}
#endif
This bug tracks deciding whether or not it makes sense to remove this exception. An example of when this would come into play would be when a keyboard is plugged into an iOS device and the user scrolls via pageup / pagedown or the arrow keys.
