Comment (by mikeperry):

 Won't applying [ChromeOnly] to the whole URL constructor also prevent
 access to the URLUtils portions of the URL API
 (https://developer.mozilla.org/en-US/docs/Web/API/URL)? Those are benign,
 and likely used elsewhere. We really want to keep this focused only on
 createObjectURL()..

 It might also be nice to have a console log message recording when/where
 createObjectURL() was called, so we can more easily inspect if it is what
 is breaking some random site..
