If we scroll on an element that is overflowing, its scroll should chain to scroll its parent when its scroll position is at the end.
In this codepen (https://codepen.io/HazzMan2409/pen/KKZxxGx) this does not happen when you scroll vertically on the child.
There is an element in between the two vertically scrolling elements that scrolls in the opposite direction, I believe it is that element that is causing the bad behavior.
Note that this behaves fine on desktop Safari.
