Custom view, on swipe shows current view as previous and next view

**Steps to reproduce the behavior:**

Here's the sandbox to test the behaviour and the actual code:
https://s9wz2.csb.app/
https://codesandbox.io/s/react-images-custom-view-s9wz2?file=/src/App.tsx

**Expected behavior:**
I expected that the swipe animation would keep as the standard one, this means if I swipe left I would see the previous view and if I swipe right I would see the next view

**Actual behavior:**
During the swipe moment we see as the previous and next view the current view

Reproduce the issue in the linked CodeSandbox, starting with src/App.tsx and the custom-view setup. Compare the swipe animation in the sandbox with the standard behavior; done means swiping shows the previous and next views rather than the current view during the animation.
