This extension seems to be working alright for me except for one bug.
If it is used in multiple instances, it won’t let me submit the form. The save button remains unresponsive. It is only when I additionally include a textarea with VE outside of the multiple instances elsewhere in the form that the save button lets me submit. I don't see any error message in the browser console.
