Removed the need for the custom "invisible" CKEditor button by adding the javascript code that checks for changes in the editor into the main javascript.
The CKEditor toolbar item was removed because the javascript code was able to be condensed into the same file. Thus, the toolbar item that was unnecessary and created an extra step for the user was removed.
Select tags were added to items to account for change.
The javascript action was added to be on change and on input.
Updated warn-before-leave.js to not unbind events and to use Drupal.behaviors for input and textareas.
Previously the unbind event would cause certain ajax and other functions added by other modules to not run. This was noticed specifically with the ajax with image fields after removing and trying to add again.
This update fixes this non-reported issue by removing the unbind function from the javascript. Drupal.behaviors was added to the inputs and textareas in order to bind the change event to all input and textareas.
Add javascript library to be check for changed input/text areas.
Add library to node form, media form, block content form.
Add ckeditor plugin for warning.
