System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 770/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 440.97

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-03-12 05:06, hash: blender/blender@375c7dc4ca
Worked: Never

Short description of error
I'm dealing with a professionally authored fbx file of a quadruped. It has been created using max.

This is what it looks like 3ds max:
max.png

I import it using the option "Automatic bone orientation" in blender.
This is what it looks like in blender:
blender.jpg

The pelvis is rotated to the side, and "RigLShoulderBlade" and "RigRShoulderBlade" point towards each other.

I have tried all other (non automatic) bone orientation options, they were even weirder than the automatic option.

Exact steps for others to reproduce the error
Click "File" -> "Import" -> "FBX (.fbx)" -> "animation.FBX"
Use the option "Automatic Bone Rotation".
Compare how the bones are oriented in comparison with the bone orientation in 3ds max.
