The help panel is a feature that allows newcomers to post questions directly to their wiki's help desk while they are in the middle of editing a page.
This feature will likely be deployed on some wikis that use Structured Discussions on their help desks (e.g. Arabic Wikipedia). This will cause the help panel to be unable to post questions. For a future release, we may want to consider figuring out how to make the help panel work with StructuredDiscussions.
Another element of this is that the help panel does not display when editing a StructuredDiscussions page. We should also think about that.
Note: this change should affect both the help panel and the help module on the newcomer homepage.
