 How to reproduce?

 1. In the **classic** editor, create a post with a gallery with one image
 and save the post.
 2. Go to the media library and delete permanently this image.
 3. Go back editing the previous post. The gallery displays "No items
 found".
 4. Attempt to edit the gallery and check the browser console.

 Here is the error displayed:

 {{{
 Uncaught TypeError: Cannot read property 'args' of undefined
     at n.<anonymous> (media-views.min.js?ver=5.8-alpha-50521:2)
     at f (underscore.min.js?ver=1.8.3:2)
 }}}

 and the trace:
