New description:

 We need to audit our oEmbed providers and determine:

  * Which ones don't support embedding an `https` URL
  * Which ones don't support embedding content over SSL

 If we have providers in core which do not support embedding content over
 SSL then we (or the WP.com team) should make contact and see if they're
 open to implementing it. This is pretty much a prerequisite for #28249 as
 it stands.
