Subject: [PATCH] For dialog without explicitly `SetMinSize`, we should use
 `SetSizerAndFit` instead, otherwise the dialog will not show correctly on
 GTK3. (OrcaSlicer/OrcaSlicer#14561) - and if `SetSizer` is called before the
 full layout has been built, then an extra `SetSizeHints` should be called
 before layout/fit so the min size can be properly set automatically based on
 children's min sizes accordingly.
