Description

Steps to reproduce:
1. Create a simple scroller and set scrollSnappingMode to either "center" "leadingEdge" or "trailingEdge" as below: (assets attached)

<s:Scroller id="imageScroller" top="61" width="100%" height="100%" verticalScrollPolicy="on"
horizontalScrollPolicy="off" scrollSnappingMode="center">
<s:VGroup id="imageGroup" height="100%" width="100%" clipAndEnableScrolling="true" gap="0">
<s:Image width="

{imageGroup.width}" height="{imageGroup.height}" verticalAlign="middle" horizontalAlign="center" enableLoadingState="true"
source="assets/Chrysanthemum.jpg"/>
<s:Image width="{imageGroup.width}

" height="

{imageGroup.height/2}" verticalAlign="middle" horizontalAlign="center"
enableLoadingState="true"
source="assets/Desert.jpg" />
<s:Image width="{imageGroup.width}" height="{imageGroup.height}" verticalAlign="middle" horizontalAlign="center"
enableLoadingState="true"
source="assets/Hydrangeas.jpg"/>
<s:Image width="{imageGroup.width}" height="{imageGroup.height/2}

" verticalAlign="middle" horizontalAlign="center"
enableLoadingState="true"
source="assets/Jellyfish.jpg" />
<s:Image width="

{imageGroup.width}" height="{imageGroup.height}" verticalAlign="middle" horizontalAlign="center"
enableLoadingState="true"
source="assets/Koala.jpg"/>
<s:Image width="{imageGroup.width}

" height="

{imageGroup.height}" verticalAlign="middle" horizontalAlign="center"
enableLoadingState="true"
source="assets/Lighthouse.jpg" />
<s:Image width="{imageGroup.width}" height="{imageGroup.height/2}" verticalAlign="middle" horizontalAlign="center"
enableLoadingState="true"
source="assets/Penguins.jpg"/>
<s:Image width="{imageGroup.width}" height="{imageGroup.height}

" verticalAlign="middle" horizontalAlign="center"
enableLoadingState="true"
source="assets/Tulips.jpg" />
</s:VGroup>
</s:Scroller>
2. Initiate a throw on the scroller and rotate device in the middle of the throw such that the item is not at "center"

Actual Results:
When rotated, the scroller does not snap at the edge corresponding to the scrollSnappingMode, instead lands at any pixel.

Expected Results:
When rotated, should land at an item snapped at corresponding edge.

Workaround (if any):
