Issue description

If you preview a camera, save a scene and restart the editor, when the editor restarts, you end up with the rotation gizmo being visible despite previewing a camera:

Interacting with the gizmo will have no effect. Normally, the rotation gizmo is hidden while previewing a camera.

I noticed this while making comparison screenshots for #101961 (comment).

Steps to reproduce

• Add a Node3D with a Camera3D child.
• Select Camera3D and click Preview in the top-left corner of the 3D editor viewport.
• Save the scene and use Project > Reload Current Project while still previewing the camera.
• When the editor reopens, the camera is still previewed but the rotation gizmo is now visible in the top-right corner of the 3D editor viewport.
