It seems that IE and Edge don't support HTML-style comments in the function constructor which arguably makes sense. An alternative would be to create an iframe with an inline script tag that has HTML comments in it, and check whether the script correctly runs (it could postMessage something back to its opener), or whether a syntax error is thrown (should be visible on the iframe's error handler even if cross origin)"}}
