Steps to reproduce:
- Visit a website with a strict CSP, like Kagi. Kagi does not allow assets outside of
self and a few whitelisted domains and JS data types to load as images.
- Try to load an asset that is outside of this allowlist, such as an image from Github using my Kagi custom CSS theme.
- Observe as Orion successfully loads the background from Github, even though the CSP should not allow Github remote assets to load.


Expected behavior:
While this was convenient to allow my remote asset to load as my Kagi background, it's a security issue. On Chromium, Orion mobile and Safari on both platforms, the image is blocked from loading.
Brave:

Safari:

Orion desktop should not allow this image to load, even in CSS, because it violates the CSP's allowlist as shown above from Google's CSP evaluator.
