    // vertical space waste for the single placeholder row is well justified by less CPU time spent on calculating
    // row heights. The documentation for the QTreeView::uniformRowHeights property even spells out the
    // implementation details: "The height is obtained from the first item in the view. It is updated when the data
    // changes on that item." These documentation guarantees are perfect for breakpointsView: if there is only a
    // single placeholder item in the tree, its row height is used as the row height; when a non-placeholder item
    // is added, the data changes and the greater non-placeholder first row height becomes used as the row height.
