How to reproduce:
1. Open the attached project "ShadowmaskBug.zip"

3. Open Lighting window (Window > Rendering > Lighting)
4. In the Lighting window set the Lighting Mode under the Mixed Lighting Tab to Shadowmask and press Generate Lighting button
5. Move the Scene View Camera using the Right mouse button

Expected result: The Scene View Camera moves, all GameObjects in the Scene View remain the same
Actual result: Moving the Scene View Camera results in Street Lamp GameObject getting rendered into the Tilemap's TerrainLit material
