Blink Commit: https://chromium-review.googlesource.com/c/chromium/src/+/518019 WebKit Source: https://searchfox.org/wubkat/source/Source/WebCore/css/parser/CSSSelectorParser.cpp#1175 Change to this: bool isHostPseudo = compoundSelector.isHostPseudoSelector(); if (isHostPseudo && elementName.isNull() && namespacePrefix.isNull()) return; if (tag != anyQName() || isHostPseudo || isShadowDOM) compoundSelector.prependTagSelector(tag, determinedPrefix == nullAtom() && determinedElementName == starAtom() && !isHostPseudo); ____ Progress following WPT: http://wpt.live/css/css-scoping/host-with-default-namespace-001.html and slightly progress this (matching Firefox but still failing): http://wpt.live/css/css-scoping/css-scoping-shadow-host-namespace.html ___ @Tim - any suggestion or we should merge since it progresses at least one WPT Test case.
