Diff view in Workflow Actions tab can break for shortcodes

[robingram]

When the workflow instance generates the diff of changed fields it will attempt to render HTML content, including shortcodes. This can break if the shortcode is rendered using a template that is in the themes folder because at the point that the diff is generated only the Admin themes are loaded.

A work-around for this is to put the shortcode templates into the app/templates folder but this might restrict the ability to use different templates in subsites.

We've worked around this in the past by temporarily setting frontend themes, rendering the template then restoring the themes config to what was there before - I think elemental area previews are an example
