I would like to ask whether there is any interest in implementing the [Drag](https://learn.microsoft.com/en-us/windows/win32/winauto/uiauto-implementingdrag) and [DropTarget](https://learn.microsoft.com/en-us/windows/win32/winauto/uiauto-implementingdroptarget) control patterns in effort to make drag-and-drop more accessible.


### Steps to reproduce

Use AIWin Live Inspect to see that Drag and DropTarget control pattern properties do not exist.
