-----------
[css-anchor-position-1] Element with display: contents doesn't establish an
anchor scope when using anchor-scope
rdar://172355302
https://bugs.webkit.org/show_bug.cgi?id=309239
Reviewed by Antti Koivisto.
anchorScopeForAnchorName figures out which ancestor establishes an anchor scope
covering the element. It reads the value of 'anchor-scope' property from the
style
returned by Element::renderStyle(). But renderStyle() is nullptr if the element
is display: contents. Change it to use renderOrDisplayContentsStyle() instead.
