In WebKit, some internal stylesheets use the legacy -webkit prefixed CSS Logical properties (e.g. https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-border-before ). Should instead replace them with the equivalent standard versions (e.g. https://developer.mozilla.org/en-US/docs/Web/CSS/border-block-start ). Probably we can convert it into a meta bug.
Created attachment 434618 [details] List of current usage outside of benchmarks and LayoutTests There isn't that much in way of usage from the look of it, practically all of it been within the UA stylesheets, which should be easy to change if anyone wants to.

Thanks Sam. Yes, that matches what Sonia found. The ones in CSSProperties.json should be kept as long as we continue to support legacy names. I think the proposal was to split the work like this: (1) Replace those related to CSS completion (bug 228548) -- it was commented there that ContextualDocumentationDatabase.js (and Jetstream benchmarks) can be ignored. (2) Replace those in internal CSS stylesheets. (3) Replace those in internal LayoutTests (that should be safe unless they test specifically legacy names). It seems there are more in imported WPT tests, but it's just because they have not been synchronized with upstream WPT.
