The following patch restores the old behaviour (at least in my use case):

// Target is a widget when a menu opens with help of an other widget
// like a button. In that case getBounds returns an object with top
and left.
var target = this._placementTarget;
- var height = target.top || target.getBounds().top;
+ var height = rootHeight - (target.top || target.getBounds().top);
this._assertSlideBar(function() {
this.setHeight(height);
});
I am not sure if this is the correct fix.
Also, I am wondering what setMaxHeigth() on a sub menu is supposed to do. At
least in the case where the list of menu buttons is higher than maxHeight()
there are no slide controls.
Cheers,
Fritz
