Images loaded twice (in my carousel)

[oudoulj]

I have a react-slick carousel loading a couple of images.
I noticed that as soon as I add
const { data, loading, error } = usePalette(url);
to my code, images are loaded twice.

This can easily be witnessed/tested on that page
https://codesandbox.io/s/react-slick-with-palette-53j28
by commenting out (or activating) line 19 (with usePalette, at this time of writing)

Is it a known issue and how can I prevent this ?
Thank you !
