When using a column layout in Qt Design Studio, whose height is bound to the visibleChildren.height property and then changing the visibility of the children items in states, the height of the column is being updated properly in the Form View / Property View of Qt Design Studio. 

However binding something else to the column.height property does not update the value of column height in the state change.

In the example the Root item height is bound to the column height, which does not update when the state is changed. I also bound the column height and item height values to the text label which also do not update when changing the states.
