Add "video playing in the background" of Opera Android and Opera Mini'.

Like Brave android browser, I suggest you to add this feature as it allows the user to start watching a certain video on a website in Opera browser, then change tabs in Opera or even hide Opera and then open another app (Whatsapp, Instagram, Twitter,...) and the audio of the video continues to be played, with the control (to go back, to play/pause and to next) through the notification: https://i.imgur.com/Es3gNyO.jpg
This is very good for listening to the video playback from www.youtube.com, for example. But it can be for any website that plays videos like twitter.com, facebook.com, news websites and many others.
Thank you
