You can only copy a scene path once.

### Tested versions

v4.4.dev7.official [46c8f8c5c]
v3.6.stable.official [de2f0f147]

### System information

win11

### Issue description

You cannot copy a scene path again using the shortcut CTRL + SHIFT + C if you copy any other text immediately after.
To copy the scene path again, deselect the scene (in the "File System" dock) and select it again, then you can copy the scene path using the shortcut.

### Steps to reproduce

1. Select a scene in the "File System" dock.
2. Copy its path using the shortcut CTRL + SHIFT + C.
3. Paste the text and verify that the path was copied.
4. Copy any other text, such as the name of a node. The scene from which you copied the path remains selected.
5. Go back to the scene that remains selected in the "File System" (Click on the scene, although it will remain selected) dock and try copying its path again using CTRL + SHIFT + C.
6. Paste the copied path and you will see that it was not copied.

### Minimal reproduction project (MRP)

...

Reproduce this in the Godot editor using the File System dock and the CTRL + SHIFT + C shortcut, following the listed steps on Windows. Trace the scene-path copy handling and the selection state after copying other text; done means the same selected scene path can be copied again without deselecting and reselecting it.
