[macOS, X11]: Initiating drag/drop from tunneling PointerPressed event has problems

[grokys]

Describe the bug

When initiating a drag/drop operation from a tunneling PointerPressed event, there are problems on macOS and X11:

• macOS: Dragging the item outside the application and dropping it causes the button to get stuck down
• X11: Any sort of drag results in the drag cursor getting stuck and not reverting to the standard pointer (repro'd on Fedora 39)

To Reproduce

The following commit reproduces the problem on the "Drag + Drop" page of ControlCatalog:
