I am using a `UIStackView` for my layout. In that stack view, when I press a button I want to hide one of the subviews. That subview contains a couple buttons and a label. My issue is that during the hide animation, the buttons and label are visible until the vertical space from the subview is fully animated away.

Is there something I can do so that when I call `subview.isHidden = true`, the subview`s contents hide immediately at the beginning of the animation instead of at the very end of the animation?
