NumericTextField clips the digit's top when focused at short heights

A NumericTextField sized shorter than the default 32 DIP control minimum (for example 200×26) loses the top half of its digits while it is focused for editing. The value renders fully when the field is not focused, and neighbouring controls at the same height (such as ComboBox and DateTimePicker) are unaffected.

Expected: the value text stays fully visible whether or not the field has focus.
