I’m testing out the awesome CSP that was added ([Mitigate XSS Attacks with Content Security Policy](https://meta.discourse.org/t/mitigate-xss-attacks-with-content-security-policy/104243)). I’ve currently had it in report only mode since release, and am seeing a large number of `CSP Violation: 'inline'` reports on /logs that are violating the script-src.

I’m guessing the best way to avoid those blocking when I move out of report only mode would be to add `inline` to the `content security policy script src` option, but since these all appear to be bundled with the main Discourse, is there a safer way to mitigate this?
