Render component without adding JavaScript code

[probablykasper]

Describe the problem

I use the render function from svelte/server to generate email HTML (with the help of https://github.com/steveninety/svelte-email-tailwind). But I'm seeing it's adding these attributes in a few places: onload="this.__e=event" onerror="this.__e=event"

Example component where this happens: https://github.com/steveninety/svelte-email-tailwind/blob/3c1103182377b0f64221b9307d4865610e15dbf9/src/lib/components/Img.svelte

Describe the proposed solution

Add an option that avoids adding extra attributes like these. I assume these attributes are hydration-related, so hydratable: false?
