That's what I'd write in the release note: Caveats ------------------ WICKET-6498 might not work as expected due to a known issues with all major browsers (Chrome, Firefox, IE > 10) which allows deferred scripts to be executed before DOMContentLoaded is fired. For this reason WICKET-6498 should be avoided for production applications and used carefully.
