Bug: Dragging attachments from Microsoft Outlook into Files windows does not work

### Description

Dragging a file attachment from a Microsoft Outlook email window into a Files window/tab doesn't work correctly.

**Note**: While dragging, I *do* see the attachment document icon with **Copy to FolderName** below it. However after releasing the mouse button, nothing happens.

Interestingly, if a file with the same name exists in the target directory, Files does display the **Conflicting file name(s)** dialog box, asking whether to generate a new name, replace the existing file(s), or skip.

So apparently, Files *does* recognize the drag operation, but when it comes time to actually copy the files, it fails silently.

### Steps To Reproduce

1. Open a Microsoft Outlook email with attachments.
2. Drag one of the attachments from the Outlook window into a Files window for an empty directory.

Alternatively:

1. Open a Microsoft Outlook email with attachments.
2. Drag one of the attachments from the Outlook window into a Files window for a directory that contains a file with the same name as the attachment.

### Requirements

I expect Files to copy the dragged attachment from Outlook into the current directory.

### Files Version

Tested with:
* 2.5.21.10
* 3.0.1.0

Windows 10 Enterprise 22H2 build 19045.3324
