I happened to have a test system with a slightly older version of master, the top commit on which is f5c8a9715d0648f946c8549e4874822af24f3880. The two commits for bug 1990306 were merged just after this.
I logged in, navigated to Acquisitions -> Load MARC Order Records
Here is a screencast that captures the console when logging out from the Load MARC Order Records page
