Comment replies (nested / threaded) stop working with this plugin active

For some strange reason, this plugin blocks the comment-reply,js script from loading just by being active. This causes nested the comment reply form to stop working in your theme, no matter what options you have enabled.

I initially laid the blame on Divi, then Yoast, then WP Core, until I disabled this specific plugin and threaded comments started working again.

I don't understand why, since this plugin is only supposed to do stuff when it's told to process the site, but it essentially breaks an active WordPress installation, so I'd advise against using it until this issue is fixed.
