Expected Behavior

Floodlight should accept signal from redstone wire connector and turn on.

Actual Behavior

While being placed under steel/aluminum/treated wood scaffolding the floodlight fails to turn on upon the signal from redstone wire. Under any other block the floodlights work as expected.

Steps to reproduce

1. Place a steel/aluminum/treated wood scaffolding.
2. Place a floodlight under the scaffolding.
3. Connect power input to the floodlight.
4. Put one redstone wire connector on the scaffolding that holds the floodlight, and another one a few blocks away with a lever near it. Link both connectors using redstone wire coil.
5. Set the first connector to "Output" mode and another connector to "Input" mode with a screwdriver. Both connectors are the same channel/color.
6. Pull the lever at the Input connector

Debug Crash Log

The game doesn't crash

This is not a bug, this is vanilla redstone mechanics.

Only solid blocks conduct signals. You'd see the same result if you used glass.
