We want to avoid encouraging the use of the
|raw filter in templates and we introduced a few back in late just before RC.
Use Safestring/Markup or just remove the
|raw filter from the templates.
Why this should be an RC target
Using |raw in templates encourages it's use and could prove to expose security holes. We actively removed these from core and heavily documented the use of
SafeMarkup::set() for this very reason.
