Changes between Version 2 and Version 3 of Ticket #36434, comment 26

v2	v3
3	3	- Restore changing of the views iframes body classes when the editor body class name changes.
4	4	- Bind the mutation observer used to resize the view iframes to the iframe window. That prevents eventual memory leak when the view is deleted.
5		- Stop triggering the `wp-mce-view-unbind` event as previously discussed.
	5	- Stop triggering/remove the `wp-mce-view-unbind` event as previously discussed.
6	6
7	7	Thinking we can keep the unbind method for now. In theory it can still be used to unbind before the view node is removed by the user (if a plugin ever needs that). This will need another look in 4.7.
