    Prevent flash of left nav panels when loading page

    In the left nav, only the panel group containing the panel for the current page
    should be expanded. However, in the Chrome browser, all other panels in the
    same dashboard are momentarily shown before being hidden. The flash of content
    happens in the time between the page's template rendering the panels and the
    JavaScript being run to hide the non-active panels. Prevent the flash by hiding
    non-active panels in the template instead of using JavaScript to hide the
    panels later.
