[v5]/[v3] Random endnode position with react-native-image-zoom-viewer

https://user-images.githubusercontent.com/292204/106319695-1bf88e00-6272-11eb-80d1-076bb82b1ae9.mov

See attached screen recording in a simulator.
I could not figure out how to debug, and why this would happen.

This is my code for `react-native-image-zoom-viewer`.
```
<>}
saveToLocalByLongPress={false}
onSwipeDown={() => navigation.goBack()}
style={{ flex: 1 }}
onChange={index => index !== undefined && setCurrentIndex(index)}
renderImage={prop => (



)}
/>
```
This is the component within the `Stack.Screen`. Any suggestions?

Start with the attached simulator recording and the ImageViewer usage shown in the issue, then inspect the Stack.Screen integration and renderImage callback. Reproduce the random endnode position; done means the image ends at a stable, correct position.
