How to prevent automatic scrolling of UICollectionView by VoiceOver?

I have a horizontally scrolled UICollectionView with a title label above it and a UIPageControl below it.

UILabel
UICollectionView
UIPageControl

When I turn on the VoiceOver accessibility feature and start traversing the screen sequentially, the collection view scrolls to the beginning or end automatically. Making the page jump off suddenly. For example, if I scroll to the 2nd page using page control, and move back to the collection view, it shows and reads the last page unexpectedly. Since I'm using the page control for navigation in the accessibility mode, I'd like to prevent the automatic scrolling.

How do I prevent or counter that?

I found an issue that seems to describe the same problem, but there's no workaround suggestion: iOS 8.4: Scroll view resets contentOffset with Voice Over enabled shortly after view appear

I encountered it on iOS 13.4.1 iPhone 11 Pro

UIScrollViewDelegate.scrollViewDidScroll(_:)

A change in the accessibility focus that triggers an automatic scrolling also triggers a call to scrollViewDidScroll(_:) in your UIScrollViewDelegate. Use that to counter the automatic scrolling effect, f.i. by setting contentOffset the way you prefer it.

You may need to detect that the scrolling was actually triggered by accessibility features, and not the user dragging or pinching. UIAccessibility.isVoiceOverRunning and UIAccessibilityFocus.accessibilityElementDidBecomeFocused() are your friends here. Beware that changing contentOffset (or zoomScale or whatever is needed) may trigger another call to scrollViewDidScroll(_:), so you need to prevent an infinite recursion.
