Text no shown when applying a non-standard vcl style

I have a TAdvStringGrid with edButton as editor style. After the button has been pressed the cell should display the word 'test'. This works fine when using the default Windows style. However, when switching the style to e.g. Lina the word 'test' is not shown.

procedure Tform.HeaderGridGetEditorType(Sender: TObject; ACol, ARow: Integer; var AEditor: TEditorType);
AEditor := edButton;

procedure Tform.GridButtonClick(Sender: TObject; ACol, ARow: Integer);
Grid.Cells[ACol, ARow] := 'test';
PostKeyEx32(VK_ESCAPE, [], False);

This was a rare issue due to subtle differences in the standard VCL TButton when being styled versus not styled.
We applied a solution for this issue and the next update will have this improvement.
