Code review comment for lp:~uriboni/webbrowser-app/media-access

Thanks for your work on this. I haven’t had a chance to test/review yet, but here is a preliminary comment: if/when https://code.launchpad.net/~osomon/webbrowser-app/apparmor-profile/+merge/272850 lands, we will need to add the 'microphone' and 'camera' policy groups to debian/webbrowser-app-apparmor.manifest.
