+ * This test downloads 2 updates sequentially, and ensures that the doorhanger
+ * and badge do what they are supposed to do:
+ *   First thing after the first download, the doorhanger should be displayed.
+ *   Then download the next update.
+ *   While that update stages, the badge should be hidden to prevent restarting
+ *     to update while the update is staging.
+ *   Once the staging completes, the badge should return. The doorhanger should
+ *     not be shown at this time, because it has already been shown this
+ *     session.
