Drag & Drop of Email item from Outlook not handled correctly

First off, this seems to describe the same issue as https://bugreports.qt.io/browse/QTBUG-73559. The issue had been closed because of missing information a long time ago.

Situation:

• Dragging an email from the inbox of Outlook for Mac (Version 16.97.2 (25052611)) to a Qt application.

Expected outcome:

• Email is saved to a local file by Outlook, and its URI is provided in the drag event.
• Note that dragging and dropping from Outlook has worked previously, but computer hardware, Outlook version and Qt version have been upgraded, all at the same time.

Actual outcome:

• The drag event is happening (and corresponding methods called) but there is no payload, i.e. `mimeData() -> formats()` is an empty list.

Minimal source code provided as attachment demonstrating the effect.
