As noted in bug 1107378 comment 19, there's at least one site (hao123) that will likely be on our prefixing "fixlist" that uses prefixed CSS animation syntax. Sample CSS, provided by Karl Dubost: @-webkit-keyframes myrotate{} -webkit-animation-name:myrotate; -webkit-animation-duration:.8s; -webkit-animation-fill-mode:both; -webkit-animation-timing-function:ease-in Source: http://s0.m.hao123img.com/static/html5-index/css/index_2c2ec19.css (karl notes that Yahoo! Japan also uses prefixed CSS animations, and they may end up on our fixlist as well.) Hence, filing this bug on emulating support for the -webkit prefixed animation properties and the @-webkit-keyframes rule, via the CSS Unprefixing service (only for sites on our fixlist of course).

Unassigning, as I'm not actively working on this at the moment. (Also, if these properties take the same syntax/keywords as our supported versions, we may just want to support them natively as aliases, instead of relying on the js-implemented CSS Unprefixing Service. That will probably happen via bug 1179408.)

Duping forward to bug 1179408.
