That behaviour is defined by the virtual "Scaled" property of a Form.
If set, all controls dimensions are proportional to the font height.
(i.e. the IDE internally divides the pixel value by 'Desktop.Scale'
before saving the form).
If unset, all controls dimensions are absolute.
If you need absolute control dimensions when making GUI, there is 99%
chance that you make something wrong.
At runtime, you have the Move() / Resize() methods that are absolute,
and MoveScaled() / ResizeScaled() that are proportional to 'Desktop.Scale'.
