NumericTextField value text is not vertically centred when the control height is increased

In the Window Designer, increasing a NumericTextField's Height above the default leaves the value text top-aligned inside the control instead of vertically centring it. The up/down spinner buttons centre correctly, so the number appears stuck to the top edge of the field. The same top alignment shows when an app sets a taller NumericTextField height at runtime. Expected: the value text stays vertically centred at any height, matching TextField and SearchField.
