https://codepen.io/jpzwarte/pen/oNwNdpN?editors=0110 In Chromium and Firefox, the background is hotpink. In Safari and STP, the background is green. This is the CSS for the web component: ```css :host([foo]) ::slotted(h1) { --background: hotpink; } ::slotted(h1) { --background: green; } ```

Gah, Ryosuke, you nerd-sniped me :) Hoping there's something in WPT for this, if not not sure I'll have the cycles to finish this soon, I'm taking a long weekend off computers :)
