This is supported in all other browsers, and it seems like it is mostly implemented in JSC as well, but this bug has been dorment for 5 months and has no assignee. Any chance you could prioritize getting this over the finish line? The feature is very hard to polyfill, so it will essentially be impossible to use before JSC supports it, and we really want to use it. Thanks!
