Conflict with WPBakery website

I have established that this plugin causes a conflict with WPBakery/Woocommerce websites, at least those created with the Werkstatt Theme.

What happens, is when it is activated, it blocks the visual editor working from the frontend, effectively rendering frontend editing useless. After all, frontend editing is intended for people who are uncomfortable with coding.

Please see the two images below, I think they clarify the existing problem.
