Impossible to have full screen from video. HTML tag is needed?

Thanks for your reply and input – I’m 100% with you, no question.
However, if there is an option in the settings, which you can use to allow running Discourse in an iframe, our customers often ask why this and that is not working -anymore- and generate unnecessary work to debug things that will NEVER work. Don’t get me wrong, I’m not discussing it with you at all and see it the same way as you do.

My suggestion would be that we add a note next to the “allow embedding site in an iframe” in the settings that this feature is not recommended and/or supported – or something like that.

Do you (guys) see it the same way? What’s your opinion on it?
