PIP mute button

Is there no way to add a mute button in the PIP window?
Why isn’t anybody responding… this is like my 3rd message about this.

This is a Chromium feature that we inherit, not one we implement. When doing some research, there is a flag #enable-experimental-web-platform-features that is supposed to add a mute button to PIP videos, but it does not seem to work for me on either Brave or Chrome.

It’s unlikely that we (Brave) will add this feature ourselves, but likely that Chrome will fix it such that it becomes the default.
