// Usually when inverting the scroll view we are using scaleY: -1 on the list
// and on the parent container. HOWEVER, starting from android API 33 there is
// a bug that can cause an ANR due to that. Thus we are using different transform
// commands to circumvent the ANR. This however causes the vertical scrollbar to
// be on the wrong side. Thus we are moving it to the other side, when the list
// is inverted.
