[Lazarus] StringGrid.LoadFromFile not loading col and row sizes

[Jürgen Hestermann]

When I store a StringGrid with

StringGrid1.SaveOptions := [soDesign,soPosition,soAttributes,soContent];
StringGrid1.SaveToFile(filename);

and reload it later with LoadFromFile() it does not reload the column widths and row heigths.
I can see that they are stored in the XML file but are ignored on loading.
Am I doing something wrong?
