Native search only sees the DOM. Once you virtualize a list or grid, offscreen rows do not exist as nodes, so Ctrl-F cannot match them unless you keep enough hidden text around to erase most of the win from virtualization.

A browser API could help, but it would need to hook into selection, focus, scroll position, and match navigation across content the page has not rendered yet. That is a much bigger contract than 'search this string', and I would not bet on sites using it consistently.
