CSP not logging in Safari

[liamfirth]

Safari doesn't log content security policy violations because it doesn't emit the securitypolicyviolation on the window object, only on the document object. Rollbar JS only listens on the window object:

this.addListener("contentsecuritypolicy", this._window, "securitypolicyviolation", null, t, !1)

rollbar.js/src/browser/telemetry.js

Line 741 in a9c567c

this.addListener('contentsecuritypolicy', this._window, 'securitypolicyviolation', null, cspHandler, false);

Confirmed in MDN Browser compatibility data mdn/browser-compat-data#12334

You can also test this in a real-life scenario, events are logged when you attach them to document but not on window in Safari (works in Chrome). In the below example nothing is showing in the Rollbar dashboard but logged to console:
