Suggested change

	This allows report objects that are {{domxref("CSPViolationReport")}} objects and {{domxref("IntegrityViolationReport")}} objects to be reported in violating pages using a {{domxref("ReportingObserver")}} (reports can be filtered on the `type` property: `"csp-violation"` or `"integrity-violation"`).

@dipikabh Yes, I think that sounds a lot more natural. See #43538

Edit ... and thanks for the review!

[dipikabh]

Just a nit, but looks good otherwise.
We can merge this for now to unblock the release notes and cleanup later if you agree with the suggestion.

Thank you!
