AutoComplete Box shows URL of Avatar instead of actual Avatar

When entering a co-author, you get autocomplete results to choose from that have their ID, slug, name ... and then it gives the URL path to their avatar (either a local image file for a Guest Author, or a gravatar.com address for other users).

I'm assuming the intent here is to actually DISPLAY the image, as the chance of showing the URL of an image file being helpful is incredibly low.


Reproduce the co-author autocomplete in the WordPress editor and trace where the avatar value is rendered in the results. Confirm the behavior for both Guest Authors and other users. Done means the autocomplete displays the avatar image instead of its local or Gravatar URL.
