 A consequence of #63018 seems to be that it pushes down oEmbed discovery
 meta tags. WordPress only fetches the first 150 KB of a page to scan for
 those. So now if you try to embed a page such as
 https://make.wordpress.org/core/2021/10/12/proposal-for-a-performance-
 team/, the tags are not be within those 150 KB anymore and embedding
 doesn't work.

 Changing priority of `wp_oembed_add_discovery_links` might help. Or
 fetching more than 150 KB, but that seems wasteful.
