See https://github.com/whatwg/html/pull/10728 for details. - Popover invokers (set declaratively or imperatively) now create an [implicit anchor element](https://www.w3.org/TR/css-anchor-position-1/#implicit-anchor-element) reference for that popover.

Some code pointers from Tim: Implicit anchor for popovers: https://searchfox.org/wubkat/search?q=symbol:_ZNK7WebCore11PopoverData7invokerEv&redirect=false Maps from names to elements here -- these would not work with implicit anchor (since the name is auto) https://searchfox.org/wubkat/rev/87ca7ad48ea92e0a1972e92dc8b28f3df63e89fa/Source/WebCore/style/AnchorPositionEvaluator.h#63 These conditionals need to be updated: https://searchfox.org/wubkat/search?q=anchorNames%28%29&path=&case=false&regexp=false
