      Description

      On windows and linux it is possible to provide custom `QMimeData` classes to provide data when they are used.

      This is relevant if data is generated on the fly (e.g. requested via network link or similar)

       

      On MacOS this would also be possible, but since `QCocoaClipboard::setMimeData` calls `QMacPasteboard::setMimeData` with `EagerRequest` the data needs to be generated immediately

      (initiating unnecessary network traffic in our case)

       

      Since this behaviour can not be changed via default Qt API this use case does not work on mac os at all.

      Changing that single line to `LazyRequest` will fix the issue.
