Not sure if that can be fixed.
The old design was a poor one and had to be fixed in a way similar to
the current one where the edit and the button are part of the
container.

Hmm... It uses same numbers as (hardcode?) in TCustomEdit for height.
Autosize needs to be true. I'll fix that. (It was false by default
because it didn't work as expected in a previous commit).

Done that in a previous version, but IIRC it then looked different
(ugly), so I changed it back to TCustomControl.
