title: How to show a Safari Extension popover programmatically
body: <p>I'm trying to write a Safari extension that consists of a button on the main toolbar with a popover tied to it, and a contextual menu item. The basic feel is modeled after the feel of the 1Password extension.</p>
  
  <p>One of the jobs of the popover is to allow a person to log in. I'm also conditionally changing the action of the contextual menu item, and if a who person isn't logged in clicks the menu item I would like to show the popover allowing them to log in, but I can't find a way to do this in the developer guides.</p>
  
  <p>How do I "show" a popover?</p>
