(👋 Hi, Chrome DevRel here)
At one point in time the mentioned
scroll-timeline-attachmentandview-timeline-attachmentproperties were part of the spec but these have since been removed. The functionality got replaced by thetimeline-scopeproperty.scroll/view-timeline-attachment: [scroll-animations] Broader scope of scroll timelines w3c/csswg-drafts#7759 (comment)scroll/view-timeline-attachmentand addtimeline-scopeinstead: [scroll-animations] Broader scope of scroll timelines w3c/csswg-drafts#7759 (comment)This PR removes references to those properties. No browser ever shipped support for these
scroll/view-timeline-attachmentproperties – they never made it past being part of an editor’s draft.
