Just wanted to say thanks for working on this -- it was a pleasant
surprise to come back from PTO and see this nearly done!

Summary:
-webkit-background-clip:text has been available for years in webkit based
browsers and has seen widespread usage on the web. This css property is
currently available in Chrome, Safari and Edge.
Bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=759568
Link to standard:
https://compat.spec.whatwg.org/#the-webkit-background-clip-property
Platform coverage:
All platforms.
Estimated or target release:
Firefox 48
Preference behind which this will be implemented:
layout.css.prefixes.webkit
Note:
The way we support this property value is a little bit different with
webkit.
After turning on layout.css.prefixes.webkit,
1. -webkit-background-clip property is supported.
2. In gecko, "text" is a valid value for *both* background-clip and
-webkit-backkground-clip.
3. In webkit, "text" is a valid value for only -webkit-backkground-clip.
If you set "text" into -webkit-background-clip and serialize
background-clip prop by style.getPropertyValue, you will still get "text",
which is problematic. dholbert gave more detail explanation on bugzilla:
