Hi Adam -
I'm unable to test this problem with your example because of the following sequence:
1. I edit my document in the editor.
2. I save the document (which saves to an actual file on the server).
3. When I come back to the editor after leaving, everything between the head tags are moved to the body.
I did double check to make sure the save feature wasn't doing this and I can confirm the HTML document on the server is saved correctly. It seems to only do this when it first loads the HTML document.
Thanks,
Andrew
