[super_drag_and_drop] Windows: dragging Outlook e-mails or attachments never reaches DropRegion (DV_E_FORMATETC 0x80040064)

[marcosgcd]

No callback from DropRegion is ever called.

Console shows following error as soon as I drag the element over my DropRegion:

It was working fine in the passt and it still works fine on MacOs.

I was on v0.8.24 upgrading to v0.9.1 did not fix the issue
