  TODO: Improve the UX for everything in here.
  It's very much placeholder, but it gets the job done. The old way of handling
  email addresses in user settings was to use dialogs to communicate state, however
  due to our dialog system overriding dialogs (causing unmounts) this creates problems
  for a sane UX. For instance, the user could easily end up entering an email address
  and receive a dialog to verify the address, which then causes the component here
  to forget what it was doing and ultimately fail. Dialogs are still used in some
  places to communicate errors - these should be replaced with inline validation when
  that is available.
