Code that you insert on this page could contain malicious content capable of compromising your account. If you import a script from another page with "importScript", "mw.loader.load", "iusc", or "lusc", take note that this causes you to dynamically load a remote script, which could be changed by others. Editors are responsible for all edits and actions they perform, including by scripts. User scripts are not centrally supported and may malfunction or become inoperable due to software changes. A guide to help you find broken scripts is available. If you are unsure whether code you are adding to this page is safe, you can ask at the appropriate village pump.
This code will be executed when previewing this page.

/*
Enables TemplateSandbox on all pages, and allows previewing with a template other than the current page being edited (e.g. preview as Template:Foo when actually editing Template:Foo/sandbox)
To use, add the following line to [[Special:MyPage/common.js]]:
importScript('User:Jackmcbarn/advancedtemplatesandbox.js'); // Linkback: [[User:Jackmcbarn/advancedtemplatesandbox.js]]
The linkback allows easier tracking of who uses this script.

Known issues:
This hardcodes contents of messages, rather than fetching them.
The span is left as a span, rather than being changed to a fieldset.
Tab indexes assume that we're the first thing after "Show changes". If we're not, tab order will be wrong. Also, it relies on non-integer tab indexes working.
