      Description

      Attempting to programmatically "scroll to bottom" using Ti 9.3.x ListView#scrollToItem on Android results in very poor ux performance with a time-consuming and choppy scrolling effect.
      Eg: $.listView.scrollToItem(0, ITEM_COUNT - 1)

      After regressing different Titanium SDK's I determined this issue first occurred in 9.3.x, where previously (ie 9.2.2.GA and before) the "scroll to bottom" was essentially instant.

      I have attached a sample project that demonstrates the problem as well 2 videos showing the sample app running on both 9.3.2.GA and 9.2.2.GA
