SerializeMesh is not keeping parent-child hierarchy

Questions
1

I am trying to SerializeMesh a mesh with children and then read it back using ImportMesh. It is working correctly when I create meshes such as Sphere, Box etc. The parent-child relationship is retained. However, if I SerializeMesh a mesh of a glb file, say, Duck.glb, then parent-child relationship is no longer retained. I have observed TransformNodes are not getting serialized. Please refer to play ground example https://www.babylonjs-playground.com/#TX92RN#1
Note, I am using SerializeMesh(rootMesh, true, true) in both the cases.
Is it not supposed to work or I am doing something wrong ?
