[SSR] Prevent ImageTool from accessing window on server-rendered components.

I'm facing an issue using this library on my Remix app. I'm wondering, why does it perform a side effect on window when I import it from my server-rendered component?

I managed to prevent the library from doing the side effect in the server by importing it on a client-only component. I'm wondering why it does immediately perform modification on the window object when you try to import it.
