Comment (by jsnajdr):

 > Another instance of this issue seems to be `wp-util.js` which uses
 Lodash

 Update: this script seems to be fine. `_` is undefined only because an
 earlier load of `load-scripts.php?load=common,underscore` failed when
 executing the `common` code, and never got to execute and initialize
 `underscore`. That's the only reason why a later `_.memoize` call fails.

 The only bug is the missing `wp-i18n` dependency in `common`.
