Bug:
6628376
The issue here is that contentX & contentY can both be 0 if we are scrolling
slowly enough as they are adjusted by the page's scale and can thus round down.
However, this would result in us falling out of layer drag mode even though
we haven't tried to scroll past the edge of the layer. Detect this case, and
stay in layer scroll mode.

final int resultY = Math.max(0,
Math.min(mScrollingLayerRect.top + contentY, maxY));
- if (resultX != mScrollingLayerRect.left ||
- resultY != mScrollingLayerRect.top) {
+ if (resultX != mScrollingLayerRect.left
+ || resultY != mScrollingLayerRect.top
+ || (contentX | contentY) == 0) {
// In case we switched to dragging the page.
mTouchMode = TOUCH_DRAG_LAYER_MODE;
deltaX = contentX;
