It's not currently possible to include these popular material design icons.
These are integrated into some CSS framework like Bulma - which is a neat JS-less framework that fits AMP ideology pretty well.
Project info: https://materialdesignicons.com/
CSS: //cdn.materialdesignicons.com/2.0.46/css/materialdesignicons.min.css
/to @cramforce @ericlindley-g for decision.
Seems similar to FontAwesome that we allow, except it is ~3x the size (85k vs 30k)
LGTM
This is just a validator change, right?
@jridgewell I believe it will require a CSP update as well.
Yep. @camelburrito did this recently for typekit.
While this is in github, it will take 2-3 weeks for it to be in production for the validator.
