@leocg I see this on multiple sites like www.vg.no and www.dagbladet.no.
Audio does not start automatically but any other media player I am listening to gets paused. And the notification bar shows some media info from Opera.
Eg listening to Spotify, going to this page: https://www.vg.no/nyheter/utenriks/i/zGl6RO/skal-ha-blitt-advart-om-kirkeangrep-av-utenlandsk-etterretningstjeneste
Then Spotify gets paused when scrolling on the page.
Not an issue on Chrome.
