Rails on top half trapdoors do not break if the trapdoor below them opens

The bug

If a rail is placed above a top half trapdoor and then the trapdoor is opened, the rail does not break until it receives a block update. This is not the case for ladders against open trapdoors when that trapdoor closes.

Credits

  2. Open the trapdoor below the rail.
    → ❌ The rail does not break.

  3. Update a block near the rail.
