Image larger than the screen inserted with drag&drop in CKEditor gets distorted (explicit image size is added by default)

This issue is related to CKEDITOR-141

Steps to reproduce :

• Choose a large image to upload on the wiki
• Upload it in the content field of a page using drag and drop
• The code of the page shows the attachment and the size of the image, ex: [[image:attachment.jpeg||height="3447" width="2292"]]
• Save and view the page
• When the browser's window is less wide than the image, the image will be shown stretched on its width (see screenshot with mobile view)
• Remove the height and width parameter from the source code solve the issue.
• The issue doesn't happen using the insert image button of CKEditor toolbar. In that case the image size it's not added as a parameter by default by CKEditor.

Tested on XWiki 9.8.1 and 10.6
