Describe the bug
When two editor are created at same page with autosave enabled, autosave text does not work on second editor ie. it is empty and never updated.
Keep in mind that autosave itself works fine, only text is not updated correctly.
To Reproduce
Create html page with two editors
Expected behavior
Autosave text displays and updates correctly in both editors.
Screenshots

Additional context
I looked at the code a little and I believe that problem is here. It seems that autosave text is retrieved via id which is problem in this case for obvious reason.
