[webvtt] Missing label [CSS-VALUES]

alastor0325 has just created a new issue for 
https://github.com/w3c/webvtt:

== Missing label [CSS-VALUES] ==
https://w3c.github.io/webvtt/#ref-for-webvtt-region-anchor-4

> Let left be leftOffset subtracted from 'viewportAnchorX vw'
> Let top be topOffset subtracted from 'viewportAnchorY vh'.

Do we miss the label **[CSS-VALUES]** for "left" and "top"? Or they're
 not related with the CSS attributes here?
Thanks!
