// 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.
