All tables are responsive regardless of selector setting

Problem/Motivation

When the module is enabled and configured, all tables become responsive, not just those added with the CKEditor Responsive Tables button.

Steps to reproduce

1. Install and enable the module.
2. Add the Responsive Table button to the CKEditor text editor.
3. View a page with existing tables. The added markup is applied to all tables making each one responsive.
Updating the Responsive Table selector settings does not appear to have any effect.
