3D objects dropped into the viewport do not respect original positioning and reset it to cursor position.

Issue description

Just as in the video, if you drag and drop a 3D scene into the 3D viewport the object's position is reset to the cursor position and the original offset in the saved scene is ignored after drag&drop is released (it is kept in while placing the scene in the viewport though).

• In 2D the offset is kept as you would expect so 2D and 3D are behaving here differently too.

Steps to reproduce

Drag and drop "drop_mesh.tscn" 3D scenes files into the viewport, move it around to see that the offset is kept properly then release the mouse button and observe how the object is reset to the cursor position.

What I'd expect is the same behaviour as in 3D that the object's offset would be kept.
