This issue is to discuss the exact specifics of the CSP violation sample. Chrome currently has some oddly specific behaviour which isn't specced. `eval('alert(1)');` -> `eval|alert(1)` - This direct eval...

`createPolicy`'s permitted policy names are inconsistent with CSP's permitted policy names

https://w3c.github.io/trusted-types/dist/spec/#dom-trustedtypepolicyfactory-createpolicy has no restrictions on the policy name, https://w3c.github.io/trusted-types/dist/spec/#trusted-types-csp-directive has. E.g. `trustedTypes.createPolicy("$")` is supported and `trusted-types $` not. https://github.com/w3c/trusted-types/issues/466 is a special case of this.

Should SVGScriptElement have an IDL way to set a trusted script value?
