Virtualize: onSwitching called with wrong index

[meowtec]

I am writing a coverflow component with infinite loop. So I use the onSwitching API combined with the Virtualize HOC, but it
got wrong index value.

const VirtualizeSwipeableViews = virtualize(SwipeableViews);
<VirtualizeSwipeableViews
  slideRenderer={() => <div />}
  onSwitching={(index) => console.log(index)}
/>

• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

index should increase when swiping to the right

Current Behavior

index always be between 2 to 4
