Comment (by joedolson):

 OK. Here's what I'm seeing, I think.

 The Media library overrides backbone.sync in `media\models\query.js`.

 Backbone uses .fetch to get data using .sync, so this is overriding the
 default Backbone return value, using `wp.media.ajax` instead.
 `wp.media.ajax` (an alias of `wp.ajax.send`) doesn't return an XHR object,
 but instead returns a promise.

 We could probably pass an option into `wp.media.ajax` that gets the XHR
 object, though I'm not at all sure what additional consequences that could
 have.

 In my quick test, I was able to get an XHR object, but I didn't see the
 header showing up, but I ran out of time today to try to track down why.
