Mousing-over an image when using the enhanced image plugin results in the dirty flag being set

[evant]

I have a site that utilises CKEditor 4.3.2 in an inline configuration. I use the checkDirty() function to check whether the editor contents have changed whenever a user tries to navigate to another page within the site, and prompt them to save if the contents have changed. This functionality worked perfectly until I replaced the original image plugin with the new widget-based enhanced image plugin.

As soon as I did this, every time I mouse-over an image, the dirty flag becomes set, even if the editor toolbar is not actually instantiated. Essentially, all you have to do to trigger this behaviour is mouse-over an image when using the enhanced image plugin, and the editor seems to think that the contents have changed. If I avoid mousing over images, the issue does not occur.

I can reproduce the problem using Firefox 26, Chrome 32.0.1700.76 and Internet Explorer 11.

In all other respects, the enhanced image plugin seems to function fine.

Fix for this issue will have to look similarly to ​https://github.com/ckeditor/ckeditor-dev/blob/master/core/editable.js#L1041-L1049. We could also think about integrating checkDirty lock with snapshots locking.
