Comment (by siliconforks):

 I was able to reproduce the issue with a production build (created with
 `npm run build`).

 Some notes on reproducing this:
 * The bug seems to occur when images are being sorted, so you need to have
 at least two images in your media library to trigger it.
 * It does not appear to make any difference whether `WP_DEBUG` is true or
 false.
 * `SCRIPT_DEBUG`, on the other hand, does make a difference - make sure
 you do not have `SCRIPT_DEBUG` set to true, because that will cause
 unminified files to be used.  (By default `SCRIPT_DEBUG` is not set, so
 this should not be an issue unless you've previously added it to your `wp-
 config.php` file.)

 It seems like the cause of the issue was a change in version 3.18.0 of
 UglifyJS to "process input as ES module by default":

 https://github.com/mishoo/UglifyJS/releases/tag/v3.18.0

 In particular it appears to be `media-views.js` that is causing the issue
 - UglifyJS is assuming that it is an ES module, which causes UglifyJS to
 generate a faulty `media-views.min.js` file.
