// So, this is a rather inelegant hack that addresses two issues.
//
// The first issue goes something like this: we use Bootstrap's
// notion of tabs to show what pane you're in. Bootstrap likes to
// highlight the active tab. Since "Settings", etc. are in our
// dropdown, therefore the dropdown is the "active" tab, so we
// draw it as though it is pushed in! However, this is
// inappropriate for what we're trying to do. (we're trying to
// give you a menu, not indicate where you are; and undoing this
// and doing all the tab work by hand is just unnecessarily
// painful.)
//
// So to get around this, we take away the "active" status of
// gear-menu every single time a tab is shown.
$('#gear-menu a[data-toggle="tab"]').on('shown', function (e) {
$('#gear-menu').removeClass('active');

// Doing so ends up causing some other problem, though, where the
// little 'active' indicators get stuck on the menu sub-items, so
// we need to flush the old ones too once a new one is
// activated. (Otherwise, once you've been to a tab you can never
// go to it again).
//
// Incidentally, this also fixes a problem we have with
// e.relatedTarget; if you don't do the clearing as specified
// above, e.relatedTarget always ends up being the last link in
// our dropdown, as opposed to "the previously selected menu
// item."
