Exporting in newer versions of UniVRM cause issues with blendshapes and scaling

Environments (please complete the following information):

• UniVRM version: 0.118.0
• Unity version: Unity-2022.3.6
• OS: Windows 10

Describe the bug

Exporting the avatar with a newer version of UniVRM causes the Mesh Bounds to increase in size and the blendshapes to be out of whack. I suspect this is due to the scaling on the avatar being weird.

For some reason on older versions of UniVRM it exports just fine. Version 0.107 exports correctly. Not sure exactly which version causes the issue though.

Adjusting the blendshapes after exporting then re-importing the VRM:

I confirmed the reproduction.
A SkinedMesh without bone weights might be the condition to reproduce this.

• root (scaling 100)
  • hips
    • spine
      • head(SkinnedMesh without bone weight but with blendshape)

I reconfirmed it.

It seems to be a regression bug caused by the processing order during normalization from v0.116.
