One possible constraint / concern here: the "search" here might need to be blocked from crossing boundaries of elements that form containing blocks for their fixed-position descendants (e.g. an element with `filter` or `transform` set to a non-default value). These properties (`filter`, `transform`, etc) are typically painted as a single layer, and are animated as a unit (e.g. if the transformed element is bouncing around the page). This proposed positioning feature could make that sort of optimization difficult, if e.g. an element with animated `transform` had a descendant that was positioned relative to some other element (particularly if that other element is also changing its position dynamically). Similarly, it's worth thinking about how this would interact with / traverse `overflow:[hidden|scroll|auto]` and `contain:paint`. -- GitHub Notification of comment by dholbert Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/5952#issuecomment-776152205 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
