Can't drag things between monitors anymore since 4.3
Tested versions
4.3 stable
System information
Windows 10 - 4.3 stable - Forward+
Issue description
Updated to 4.3 and now I can't drag nodes between monitors. I have my setup as in the image (central editor in the middle and filesystem, scene and Node Inspectors on the left monitor) and if I have nodes in my scene inspector that I want to drag to my script in the central monitor it won't take many times. I saw this mentioned on Reddit as well.
Same happens if I have an object in the filesystem into a node in the node inspector.
(screenshot is on 4.2.1 because I had to revert to continue working)
Steps to reproduce
Drag node from scene inspector in one monitor to code editor on a different monitor
Minimal reproduction project (MRP)
N/A
From my tests, the problem in 4.3 compared to 4.2.2 is that the detached dock window must first have the focus when you initiate the drag, or it will not work, does not matter if it is between different monitors or not. To be clear, to make it work you must first click the dock window to make it take the focus, then click again to initate the drag. Second issue that also affect 4.2.2 is that the drag preview that follow the mouse cursor is not working between windows either.
@desastreger Can you try following the same steps on 4.3 dev/beta/RCs to determine when the regression started? You can download them here.
Since window focus matters, I thought I would test this to see if anything was different https://github.com/godotengine/godot/pull/95606.
In 4.3.stable:
- When Scene tab is attached, drag and drop to Script tab works.
- With floating Scene window on the same display as Script tab: drag and drop works.
- With floating Scene window on another display, Scene window focused: drag and drop works.
- With floating Scene window on another display, Scene window unfocused: drag and drop does not work. No reference to a node is placed in the scripting editor. Also, releasing LMB on the main display does not actually end the dragging action. This is still visible:
With the artifact from this PR: Same behavior in all cases.

I'm able to reproduce on only one monitor. Windows 11 Godot 4.3 rc3
If Destination has focus before draging, it's working but the cursor is incorrect when the drag&drop could be completed.
