Deconstructing solar panels does not restore the decor penalty of heavy-watt wire.

When heavy-watt wire is built inside Solar Panels, the decor penalty from the heavy-watt wire is hidden, as expected.

When a solar panel is dismantled, the heavy-watt wire gets exposed, but does not start producing a decor penalty until the next save/reload.

Attached screenshot shows decor while the game is unpaused.
