TCoolBar band resizing problem in Delphi 10.3 - delphi

Question

I put a TCoolBar component into a brand new project in Delphi 10.3. There are some bands in a row. When I resize one band, the others on its right in the same row resize too. I can decrease or increase the band size, the others on the right always grow by the difference. If I resize the form all the band gone wild. They all increase their sizes.
The error does not occure if I create a band by the band editor. It occures when I drop down some TActionToolBar into the TCoolBar.
The CoolBar AutoSize does not set. The bands or TActionToolBar has not a property like this.
The pas file:
unit Unit2;
interface
uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.ToolWin, Vcl.ComCtrls,
Vcl.PlatformDefaultStyleActnCtrls, System.Actions, Vcl.ActnList, Vcl.ActnMan,
Vcl.ActnCtrls;
type
TForm2 = class(TForm)
ActionManager1: TActionManager;
CoolBar1: TCoolBar;
ActionToolBar1: TActionToolBar;
ActionToolBar2: TActionToolBar;
ActionToolBar3: TActionToolBar;
ActionToolBar4: TActionToolBar;
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form2: TForm2;
implementation
{$R *.dfm}
end.
The dpr file:

Is there any solution for this problem?
