1) Add the table controls with this plugin (only the table controls in my case, although I do not think it will matter)
2) Either create a new post or edit an existing post and add a table with these controls, then save and exit
3) Enter the post again but do not modify anything. Simply click on another element in the dashboard left-hand navigation to leave the post. The post prompts the user to save, as if changes have been made.
I have tested this without the plugin and there was no such prompt.
