Those properties were designed for aural browsers using speech synthesis
to read the content of a page, not to control multimedia in a page
itself. Also, attempting to hijack those properties for use with
multimedia content could create difficulties as you would have to define
how the HTMLMediaElement's volume and muted properties interact with
those CSS properties, if at all.
