Possible Bug with ECS transforms system with preview 11

While pouring through transform system code, I noticed something likely a bug when a child have only scale component. Following is transform system preview 11 line 507 to 518

Spoiler: Code

Code (CSharp):

1.                 if ((!chunkPositionsExist) && (!chunkRotationsExist) && (chunkScalesExist))
2.                 {
3.                     for (int i = 0; i < parentCount; i++)
4.                     {
5.                         chunkLocalToWorlds[i] = new LocalToWorld
6.                         {
7.                             Value = math.mul(float4x4.translate(chunkPositions[i].Value),
8.                                 float4x4.scale(chunkScales[i].Value))
9.                         };
10.                     }
11.                 }

notice that it reads from "chunkPositions" when "chunkPositions" does not exist.
