title: How to make buttons fill vertically in a NSStackView with a fixed height

  <p>The NSStackView shown above has top/leading/trailing constraints, a proportional height to its superview, and is set to Align Top and Fill Equally. I want to have the buttons stretch vertically to fill the height of their stack view. How can I configure this with a NSStackView? Or do I have to add constraints on the buttons?</p>
