This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Chrome 19 dev serializes the 'clip' property with no commas, like "rect(1px 2px 3px 4px)". IE 10 Developer Preview, Firefox 13.0a1, and Opera Next 12.00 alpha serialize it with commas. Please clarify that it has to be serialized with commas, which matches the majority of browsers. (CSS 2.1 doesn't even require that the comma-less syntax be parsed by UAs.)
This was already defined to serialize with commas, but I tried to make it clearer. https://dvcs.w3.org/hg/csswg/rev/919231f82d3b
