Layout minimum size does not work

It is not possible to constrain a layout to be smaller than the preferred size of its children, and Layout.minimumWidth has no effect. Setting implicit size instead of preferred size makes no difference.

Attached is a sample containing rectangles anchored in various ways inside the layout. When the size of the layout is smaller than their preferred width, the layout will still use space according to the largest child's preferred size, positioning all others accordingly. It should shrink the items to fit the available space.
