Is there any way to check if the particular arrangement is scrolled

Here we go again, I know it's something with scroll handler again, please do let me know if you have any idea how can I check?

Currently, seems that this extension's RegisterScroll only works with scroll arrangements, but give it a shot. You can use CanScrollUp to see if the user has scrolled to the top of the scroll arrangement, or RegisterScroll to start detecting scroll events.

prevX and prevY are previous dimensions.
