Cannot add content to admin sidebar without breaking layout

[Ben Davis]

If I want to add content to the sidebar on the admin index page, I would normally override admin/index.html like so:

{% extends "admin/index.html" %}

{% block sidebar %}
  <p>Other stuff</p>
  {{ block.super }}
{% endblock %}

However, using {{block.super}} breaks layout because it contains <div id="content-related">, which is floated right to achieve the sidebar look. Adding any content before this will shift the sidebar to the bottom of the page.

Ideally, the sidebar block should be defined inside <div id="content-related">, so that template authors can add content to the sidebar.
