[webvtt] Ruby text has no background by default

zcorpan has just created a new issue for 
https://github.com/w3c/webvtt:

== Ruby text has no background by default ==
https://w3c.github.io/webvtt/#applying-css-properties

> The background shorthand property on the WebVTT cue background box 
must be set to 'rgba(0,0,0,0.8)'. [CSS3-COLOR]

https://zcorpan.github.io/live-webvtt-viewer/#vtt=WEBVTT%0A%0A00%3A00%3A00.000+--%3E+00%3A00%3A10.000%0A%3Cruby%3Efoo%3Crt%3Ebar%3C%2Fruby%3E%0A

Check in Firefox. The ruby text is white on white background. Maybe 
<rt> should have a default background also.
