Use dockpanelsuite's border in float windows

https://docs.dockpanelsuite.com/tutorials/customizing-floatwindow.html
The above post explained on how to customize float window to have maximize buttom on the title bar.
Is their any posibility to hide the winforms defaul title bar and use dockpanelsuite's caption bar instead in float windows
I can simply hide the default title bar by setting FormBorderStyle = FormBorderStyle.None;
However, the windows become undraggable and I can't find how to set dockpanelsuite's caption bar to show

Modifiying the dll HASCaption() does allow the caption bar to appear when nested panel is less than or equal to 1
However, simply setting FormBorderStyle = FormBorderStyle.None; leads to an unwanted excess white area at the right and bottom of the form.

So the CustomeFloatWindow method as described in the documentation seems to only apply FormBorderStyle but does not re-draw the form
Simply setting FormBorderStyle = FormBorderStyle.None; result in unwanted excess white area at the right and bottom of the form.
Which looks like the above image.
In order to have it looks properly, you should modify the dll by doing these two things:
Change DockState == DockState.Float && FloatWindow.VisibleNestedPanes.Count <= 1
to DockState == DockState.Float && FloatWindow.VisibleNestedPanes.Count < 1 in DockPane.cs
Change FormBorderStyle = FormBorderStyle.SizableToolWindow;
to FormBorderStyle = FormBorderStyle.None; in FloatWindow.cs
Compile and replace the WeifenLuo.WinFormsUI.Docking.dll

Result looks like this.
I am not sure if this is possible to be accomplished through System.Reflection.
Definitely be much more convinient if this is added in the future version of Dock Panel Suite.

Is it possible to make FormBorderStyle = FormBorderStyle.None sizable?

The mystery around FormBorderStyle.None is a WinForms nightmare for decades, so I don't expect this library be able to help much.
