On IE11 when you get the user prompt
Only secure content is displayed. #Show all content#
the readyState is never changing, it is always on loading
and the events do not fire either. Once the user clicks Show all content
it works fine.
Unfortunately I have a site where I can't resolve the non SSL scripts and images (third party sites and user content) and it is fine if it isn't loaded, but I need the DOMContentReady event for important and securely loaded JS. Are you aware of any workaround?
