ScrollView produces jittery animation when playing PostPointerUpAnimation

In line 1574 of “ScrollView.cs” (https://github.com/Unity-Technologies/UnityCsReference/blob/2023.2/ModuleOverrides/com.unity.ui/Core/Controls/ScrollView.cs#L1559)) PostPointerUpAnimation is executed every 30ms (schedule.Execute(PostPointerUpAnimation).Every(30)) which produces jittery animation.

The user suggested changing “.Every(30)” into “.Until(() => false)” which would execute animation every frame and produce far better results.
