Background tabs play when regain focus

[ptankov]

1. I open several YouTube videos in several background tabs.
2. I never click on those background tabs.
3. I bring some other program into focus, for example, my email client or the terminal or whatever.
4. I go back to Vivaldi and make it the active window, i.e. bring it into focus again.

Result: ALL of the background YouTube tabs start playing simultaneously.

This is a bug and it started happening recently.
