It seems that chrome:// image URIs can be loaded in content. That's been pretty handy as we start using Storybook as a gallery of our reusable UI components for things like icons.
I've noticed, however, that mask images aren't loaded. Is that intentional? Presuming that exposing chrome:// images is okay, can we expose them for image masks as well?
See attachment.

In the attached document, there should be a second image below the first little chevron here: I'd expect to see a little red arrow below the black one.

This is intentional, mask-image has cross-origin restrictions: https://drafts.fxtf.org/css-masking-1/#sec
We could special-case chrome:// I guess, but it's unclear what the security implications of that is at a glance. If you really need it, please reopen and we can look into it, but we should probably loop in some of the security folks before doing so.
