Did you perhaps forget to set translatesAutoresizingMaskIntoConstraints = NO
on one of the views you return it defaults to YES on newly-created views)? This
constraint is used by the layout system to apply heights you specify elsewhere.
I *think* it is one for non-AutoLayout views. If I'm misremembering, check for
any other views that arrange their subviews, like NSStackViews.
