Grid on Svelte completely broken

[doncezart]

Description

The MasonryInfiniteGrid on a Sveltekit website is completely broken. Not only the images aren't getting resized, they don't respect the parent div. More than that, behind the images in the grid I can see a different column of images that respect the parent div but they overflow to the right because they're also not getting resized.

I've tried many different methods of loading the images and settings for the grid and nothing works. People on several dev discord servers couldn't find a fix.

Steps to check or reproduce

You can see the live website at https://ceza.ro/grid (I recommend zooming out)
