Comment (by peterwilsoncc):

 Replying to [comment:7 burtrw]:
 > @johnbillion Thanks for following up! Our testing is that it looks like
 WordPress allows for better custom styling if the allow list autodiscovery
 works. Without it, our embeds get an extra border, which really doesn't
 look good, but we haven't found where that is coming from.

 For sites using auto-discovery, the style tag is stripped from the iframe
 but the `frameborder` attribute is permitted

 Are you able to test the embed code using the following:

 {{{
 <iframe src="https://gravatar.com/matt.card" width="351" height="436"
 frameborder="0"></iframe>
 }}}

 I'm seeing a few CSP errors visiting the cards but they don't appear to
 affect the display.

 To use auto-embeds, links will need to go to the same domain as the embed
 so you'll need to do redirects. Eg `gravatar.com/matt/go/x` or
 `gravatar.com/matt/go/http://customlink.example.com/` -- see this

 develop/blob/415c9f6bb488facb48c44141a7ed4ffc2444e22a/src/js/_enqueues/wp/embed.js#L77-L83
 code in the embed.js].
