Strange behavior while using pinch gesture detector or scaling/translating inside item component

[mexysfr]

Current behavior

Hello,

I've noticed a strange behavior when using a pinch gesture detector with Flashlist.

The items in my list are simple: a header, an image and a footer.

The image is wrapped in a <SnapbackZoom> component from this lib, simply responsible for listening on a pinch event and then scaling and translating that image during the pinch.

In a random way, when a first image is zoomed, the size of a second image considered by the Flashlist a little further down the list is for some reason increased.
This behavior persists even when the second image is removed from the viewport.

By reloading the list (reloading the application), the second image returns to its original size, until the first image is zoomed in again.

Expected behavior

When an image is zoomed (scale, translate X, translate Y), the size of the other images in the list should not change.
