API required // Google Maps Element and such stuff not handled by the external content optin as it's not loaded via an iframe

I guess this can only be properly solved by providing an API to our code, so that other scripts can use the overlay mechanism on purpose inside the code. This can be tested in our demo pretty well. Also the problem appears on Benediktbeuern. They have scripts that are inside the HTML that should load only if external content is accepted. This scripts are setting cookies and can't be easily moved into the tool as they use document.write.
