// The item selection timer has fired, we might have to readjust the
// selected item. There are two cases here that we are trying to deal with:
// (1) diagonal movement from a parent menu to a submenu passing briefly over
// other items, and
// (2) moving out from a submenu to a parent or grandparent menu.
// In both cases, |mTimerMenu| is the menu item that might have an open submenu and
// the first item in |mPopups| is the item the mouse is currently over, which could be
// none of them.
//
// case (1):
// As the mouse moves from the parent item of a submenu (we'll call 'A') diagonally into the
// submenu, it probably passes through one or more sibilings (B). As the mouse passes
// through B, it becomes the current menu item and the timer is set and mTimerMenu is
// set to A. Before the timer fires, the mouse leaves the menu containing A and B and
// enters the submenus. Now when the timer fires, |mPopups| is null (!= |mTimerMenu|)
// so we have to see if anything in A's children is selected (recall that even disabled
// items are selected, the style just doesn't show it). If that is the case, we need to
// set the selected item back to A.
//
// case (2);
// Item A has an open submenu, and in it there is an item (B) which also has an open
// submenu (so there are 3 menus displayed right now). The mouse then leaves B's child
// submenu and selects an item that is a sibling of A, call it C. When the mouse enters C,
// the timer is set and |mTimerMenu| is A and |mPopups| is C. As the timer fires,
// the mouse is still within C. The correct behavior is to set the current item to C
// and close up the chain parented at A.
//
// This brings up the question of is the logic of case (1) enough? The answer is no,
// and is discussed in bugzilla bug 29400. Case (1) asks if A's submenu has a selected
// child, and if it does, set the selected item to A. Because B has a submenu open, it
// is selected and as a result, A is set to be the selected item even though the mouse
// rests in C -- very wrong.
//
// The solution is to use the same idea, but instead of only checking one level,
// drill all the way down to the deepest open submenu and check if it has something
// selected. Since the mouse is in a grandparent, it won't, and we know that we can
// safely close up A and all its children.
//
// The code below melds the two cases together.
