Speculation Rules: ensure that non-visible anchors with visible descendants
get prefetched
https://bugs.webkit.org/show_bug.cgi?id=306860
Reviewed by Alex Christensen.
Anchor elements with `display: contents` may not be visible but could have
visible descendants.
The current speculation rules logic doesn't account for that, and prevents
prefetches on such elements from working.
This fixes that by looking at their descendants and seeing if they are rendered.
