Steps to reproduce:
The KPN iTV website (https://tv.kpn.com/) doesn't play video. When starting a stream it plays for half a second before cutting out and going back to the previous screen (I've attached a video below). I've tried both compatibility mode and disabled content blockers, but neither fix anything. It works perfectly fine on Safari.
I expect videos to play and stream.
