I think if Chromium is interested in reintroducing the rb element to the standard, it'd be good to discuss that with the standards community, and work on a proper change to the HTML Standard. In the meantime, I'd suggest not introducing any default CSS changes that only work with elements marked as obsolete in the HTML Standard. > > > Blink componentBlink>Layout>Ruby > <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3ELayout%3ERuby> > > Search tagscss <https://chromestatus.com/features#tags:css>, ruby > <https://chromestatus.com/features#tags:ruby> > > TAG reviewNone; Firefox already shipped this. > > TAG review statusNot applicable > > Risks > > > Interoperability and Compatibility > > This feature does not affect most <ruby> usages on existing pages. > However, the rendering results may change if the `display` property value > of <ruby> or <rt> is set to a non-default value because ruby rendering is > triggered by the new `display` value, not the tag name. > https://chromestatus.com/metrics/feature/timeline/popularity/3282 At most > 0.07% page views might be affected.
