Description
Current behavior
I have a list with maintainContentVisiblePosition prop and autoScrollToBottomThreshold set to 0.2. When backward and forward pagination is enabled, it might happen that they are both triggered at the same time, for example, when we render a short list. In such a case, autoscroll to the bottom doesn't work.

Expected behavior
Autoscroll to bottom should work when both paginations are triggered.

Research direction
Start by running the linked rn-playground fixture app and reproducing the short-list case on iOS with maintainContentVisiblePosition and autoScrollToBottomThreshold set. Trace the handling of simultaneous backward and forward pagination; done means autoscroll reaches the bottom when both pagination directions trigger.
