[PATCH v2 0/1] MR4663: winex11: Do window search if IDropTarget::DragOver() returns DROPEFFECT_NONE.

[Akihiro Sagawa (＠sgwaki)]

Fixes a regression from 1d337249f16ed61163315019f5dbbe4db3386390.

Prior to the commit, we were solving this case in a different way.
If `IDropTarget::DragOver()` returned `DROPEFFECT_NONE`, `X11DRV_XDND_DROPEFFECTToXdndAction()` would convert it to `XdndActionCopy`.
