Custom UIStackView not displaying arrangedSubviews correctly in iOS 17

I'm encountering an issue with a custom `UIStackView` implementation in my iOS 17 app. The stack view seems to ignore the `isHidden` property of some of its arranged subviews, causing them to be displayed even when I set `isHidden = true`. My setup involves a vertical stack view containing several labels. Here's how I initialize and add the labels: ```swift let stackView = UIStackView() stackView.axis = .vertical stackView.spacing = 8 stackView.translatesAutoresizingMaskIntoConstraints = false let label1 = UILabel() label1.text = "Label 1" stackView.addArrangedSubview(label1) let label2 = UILabel() label2.text = "Label 2" stackView.addArrangedSubview(label2) let label3 = UILabel() label3.text = "Label 3" stackView.addArrangedSubview(label3) ``` Later in my code, I need to hide `label2` based on some condition, so I do the following: ```swift if someCondition { label2.isHidden = true } ``` However, `label2` still appears in the stack view layout, and I can see the gap where it should be, which is unexpected. I've double-checked to ensure that `label2` is indeed the correct reference and I even tried calling `stackView.layoutIfNeeded()` after setting `isHidden`, but it didn't resolve the issue. I also confirmed that there are no constraints conflicting with the stack view's layout. Is there anything specific to iOS 17 or changes in `UIStackView` behavior that I should be aware of? Any advice on how to properly hide the arranged subviews would be greatly appreciated.
