The WYSIWYG editor transforms the content into HTML code when reloading certain types of documents

This happens when the exact HTML leading to the WYSIWYG is dynamically changed via JavaScript and the WYSIWYG reloads. For example, if the field being edited is hidden and then re-displayed.

To reproduce:

• import the attached XAR
• edit it in Inline mode
• click on Show, see proper content
• reload, click again on Show, see HTML code
• repeat, each time the HTML is escaped one more time

The same thing happens with Save & View + hitting the browser's back button.
