Hi!
That was a test query by me, after the change. That means, it should be working.
I believe the cache is still serving the old/unchanged files. I just checked, and the unchanged versions are served on incognito, and sometimes when logged-in as well. Make sure to clear all layers of cache (page, minify, CDN, Cloudflare etc..), that will update the code to the changed version.
You can also safely update the plugin to 4.14, it was released yesterday, and this change is included in it. Don’t forget to clear the caches afterwards as well. That should hopefully do the trick.
