Fizz currently generates inline scripts. If you have a Content Security Policy that blocks it, you need to provide a
nonceattribute to it to allow those scripts. This just adds an option to pass through such an attribute.However, a better strategy is probably that we expose an external script that can be loaded onto the page early through a
srcwith a mutation observer that detects segments that we've inserted and runs the appropriate commands. That way we don't need to use inline scripts for this. It's also closer to what we want the ideal built-in feature for this in the DOM would look like so it'd be more of a polyfill.However, it might still be better to use inline scripts for the cases where it is allowed and you haven't already loaded the script into cache. Also, if you already have a nonce anyway it might be better.
