Note that if you're cloning UXML you can't set pickingMode in a constructor, because the Factory's UxmlTraits will come along and overwrite it.
See my forum thread.

To fix this issue you can create your own UxmlTraits, eg.

public class BetterUxmlTraits : VisualElement.UxmlTraits
{
	public override void Init(VisualElement ve, IUxmlAttributes bag, CreationContext cc)
	{
		PickingMode prevPickingMode = ve.pickingMode;
		base.Init(ve, bag, cc);
		// Respect the pickingMode set in the constructor.
		if (!bag.TryGetAttributeValue(m_PickingMode.name, out _))
			ve.pickingMode = prevPickingMode;
	}
}

which you can subclass and provide to your factory arguments.

Sadly in 2023/6+, due to all this being code generated from attributes I'd probably recommend a different workaround.
