It now utilises the
[`IDropTargetHelper`](https://learn.microsoft.com/en-us/windows/win32/api/shobjidl_core/nn-shobjidl_core-idroptargethelper)
in drag and drop events to render the proper item drop cursor icon which
includes the thumbnail when available and action text. Also swaps the
drop effect from `DROPEFFECT_LINK` to `DROPEFFECT_COPY` to match other
Windows application behaviour.
