Allow the user to change the minimum size of resizing components - whether it
should be 0, or whether component's minimum size should be honnored. Perhaps the
default state then should be 0 for components whose minimum size depends on
content, like labels, buttons, comboboxes. The problem is when the content
(text) changes so it does not fit in the component - then it perhaps should be
cut, not the component should grow. However, in general both cases are valid.

See also issue 68612 - which we fixed just by treating the combobox specially.
But the same problem may happen e.g. with a label showing file names (paths) -
that is supposed to cut the text if it is too long, not to grow.
