Scaffolding does not break at 0 heights

Summary:

At 0 altitude and -64 altitude, scaffolding has no gravity whatsoever.
At these heights, you cannot make the scaffolding fall or break on its own.

At -64 altitude, no blocks have gravity MCPE-8758 (Won't Fix? 😕). But at 0 height, only the scaffolding has no gravity.

Steps to reproduce:

1. Take scaffolding.
2. Place the scaffolding at 0 height.
3. Break any support blocks near them.

Observed results:

Scaffolding will fly without any blocks (and you can't make them fall / break).

Expected results:

Scaffolding will break / fall at any height.
