AppWindowTitleBar.SetDragRectangles doesn't work in Windows App SDK 1.4.230822000

[Starcloudsea]

Describe the bug

After updating to Windows App SDK 1.4.230822000,
AppWindowTitleBar.SetDragRectangles(new RectInt32[]{new RectInt32(800, 0, ScreenWidth - 80, 40)});
It no longer has the effect of changing the title bar draggable area, and every time I use this method again, the Windows App SDK uses the default title bar draggable area instead of my customized title bar draggable area.
Hopefully Microsoft can fix this!

Steps to reproduce the bug

1, Install Windows App SDK 1.4.230822000 NuGet package for your "Blank Project (Packaged)".
2, use AppWindowTitleBar.SetDragRectangles(new RectInt32[]{new RectInt32(800, 0, 80, 40)}); to set the draggable area of the title bar.
3, run the app, move the mouse to the upper left corner of the app and double click.
4, you will see the app is maximized, which means this method is not working.
5, back to Windows App SDK 1.3.230724000, run the app again, move the mouse to the upper left corner of the app and double click.
6, you will see that the app is not maximized, which means this method worked.

Expected behavior

Run the app, mouse over the top left corner of the app, double click, the app is not maximized.

Additional context

By the way, I'm not sure if anyone has mentioned this, and I'm not sure if Microsoft has a replacement method, because I've searched for it many times, and I haven't found any information about it at all, so if there is a replacement method, I hope you guys can let me know, thanks!

Sorry, I forgot about that.

InputNonClientPointerSource.
The annoying thing here is that SetDragRects is marked as deprecated in the metadata and it does name InputNonClientPointerSource as the replacement.

@DarranRowe How it use? I also set AppWindowTitleBar.SetDragRectangles and it does nothing

As stated in the release notes, you might have to call

AppWindow.TitleBar.IconShowOptions = IconShowOptions.HideIconAndSystemMenu

to disable the system menu when clicking at the upper left corner of the window.
