The easiest fix here is to ignore Namespaces with the help panel disabled in both reading and editing mode when we're in the Suggested Edits mode. That way, Help Panel would get enabled for Suggested edits, preventing T377783 from happening again.

Alternatively, we can prevent admins from even selecting (Main) in Namespaces with the help panel disabled in both reading and editing mode. That is more difficult to accomplish, but I can't really think of a reason why someone would want to disable Help Panel in the main namespace (aside from wanting to disable it completely, including in the main namespace).

I'm leaning towards going through the easy route here and always enable Help Panel when in a Suggested Edit (even when it would be disabled otherwise), as Suggested Edits do not really make any sense without Help panel (in fact, as T377783 shows, they do not work without Help panel).

@KStoller-WMF, do you have any thoughts on this?

I agree; this seems like the logical solution. I also think it's the better solution for end users: I would prefer we don't limit an Admin configuration option that could have a legit use case.

Thanks Kirsten! In that case, this is now actionable.
