Bug 253177 – WebKit doesn't correctly suppress block-axis margins on nested <dl> elements.

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Emilio Cobos Álvarez (:emilio)]

It seems WebKit and Blink only partially implement the lists section of the HTML spec, see https://html.spec.whatwg.org/#lists

 * https://searchfox.org/wubkat/rev/b6cbf096c512d8334fe4151843acab55272492ae/Source/WebCore/css/html.css#364
 * https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/core/html/resources/html.css;l=364;drc=04a73d3d930f7d80d7eb7c38977798b2a93eccec

Which means that test-cases like https://bug1817950.bmoattachments.org/attachment.cgi?id=9320609 render differently in Firefox.

The spec is rather clear.
