[4.1 Alpha 3] Template code editor illegal offset exception 'return' when previewing/saving. Preview content not updating until create new page button pressed.
In one specific area, If I attempt to create a template, an error exception is displayed when previewing or saving the page:
ErrorException: [E_WARNING] Illegal string offset 'return' in src/addons/vw/vw/_core/model/parser/handle/vw.php at line 95
This exception occurs even if the editor is left empty. It is thrown also regardless of whether the page title field has been filled in or not. In other words, the error occurs before the form is being validated for the required fields. Normal page content types (but still with template code editor) do not run into the error exception.

But back to the one area with issues. I have run into an issue where the template code editor is shown on the edit screen, regardless of the content type. Page, Category, Book, Attachment, Anonymous Page are all affected. Other areas do not experience this behaviour and the editor changes to Froala (bbcode) as is appropriate for the content type.
EDIT: As identified in the comments below, this part isn't a bug as it relates to parsing HTML content in this area.
FWIW, the funky template problem that I reported in
issue 5735 belongs to this same Area. Could these two issues be related in some way?
The VaultWiki installation that this was experienced on is XF2.1 based and for testing only. I will likely reinstall VW from scratch once a non-Alpha version is available. I don't need to retain any information from the test install.

This test area is a dedicated place for templates and some templates do need to parse HTML.
