(set-volume! this val)Property.
The media.MediaTrackSupportedConstraints dictionary's volume
is a read-only Boolean value which is present (and set to true)
the object returned by media.MediaDevices.getSupportedConstraints()
and only if the user agent supports the volume constraint. If
constraint isn't supported, it's not included in the list, so
value will never be false.
volumeConstraintSupported = supportedConstraintsDictionary.volume;

The media.MediaTrackSupportedConstraints dictionary's width
is a read-only Boolean value which is present (and set to true)
