I am using panels to override the user edit page (/user/*/edit) to add a block with a form in it. However I wanted to maintain the existing user edit form, including the password, username, etc. When I overrode the page, I was able to add my block, but lost the original user edit form. I've tried adding the various widgets from the 'User' category (user profile, Profile:Main Profile, etc) on the 'Content' section of the new variant, but they just seem to contain various bits of user information, and none of them add the user form.
How can I add back the user edit form to an panels-overridden user edit page?
