//
// (a) each innermost div contributes an explicit height: 20px value.
// (b) the .overflow div contributes 2px of border (1px top + bottom),
// plus the height of its scrollbar from overflow:auto.
// (c) the .flexbox div contributes 10px of border (5px top + bottom).
//
// So, the total height is 20px + 2px + 10px + scrollbarHeight,
// which simplifies to 32px + scrollbarHeight.
//
// Analogously, the same logic applies for nodes where width is tested.
