The WYSIWYG editor doesn't use the syntax specified in the template, when creating a new page, before the page is saved

Follow this steps to reproduce:

• Create an AppWithinMinutes application that has a TextArea or Content field
• Make sure the preferred editor for the current user is WYSIWYG
• Enable the Plain 1.0 syntax from the administration and set it as default
• Create a new entry for the application you created in the first step, but don't save
• Check how the Source button works
• Insert a macro
• Attach a file

It seems that the WYSIWYG editor uses the default wiki syntax (Plain 1.0) instead of the template syntax (XWiki 2.1) before the document is saved.
