Headers Won't Stick to Areas
When creating a header integration for a wiki area, after the page reloads it looks like no header was added. Clicking Manage again shows no existing header, but if we look in the database, one exists.
The template for the form uses the wrong nodetypeid when applying headers to Area-type pages (it assumes it's a regular page). This is fixed in the next release. Any ghost headers created by this bug will be enabled by the upgrade script.
