--key SECRET parameter makes toolbar symbols not load and redirects to [...]/edit, not [...]/view.

https://github.com/audreyt/ethercalc/issues/1#issuecomment-5246984 says:

 To enable this mode, start ethercalc with a "--key" parameter:

      ./bin/ethercalc --key 85b5dd7a-8afe-11e1-bca8-002332d309a4

  Under this mode, /:room simply redirects to the /:room/view URL.

But I will be redirected to /:room/edit, have edit rights, AND the toolbar symbols do not load (without --key they load).
