Hi Team, While looking into default UA stylesheet of 'ladybird' browser, I noticed that they are following all UA stylesheet rules and noticed, we have added following: ____ legend[align=left i] { justify-self: left; } legend[align=center i] { justify-self: center; } legend[align=right i] { justify-self: right; } ____ Web-Spec: https://html.spec.whatwg.org/#the-fieldset-and-legend-elements In my local testing, adding them leads to progress following test case: http://wpt.live/html/rendering/non-replaced-elements/the-fieldset-and-legend-elements/legend-align-justify-self.html I think we should go for it and get all those WPT wins unless if there is genuine reason that we don't want to do them. Thanks!
