System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.66

Blender Version
Broken: version: 2.83.0, branch: master, commit date: 2020-06-03 14:38, hash: blender/blender@211b6c29f7
Worked: 2.79

Short description of error
Meshes parented to bones have an offset in the exported .fbx files.

Exact steps for others to reproduce the error
1.- create an armature with 2 bones, and two meshes.
2.- Parent/bone relative each mesh to a bone in pose mode, selecting in only one "keep transform" (to verify it doesn't have effect on the exported .fbx).
2.- Export to .fbx file (uncheck "add leaf nodes").
3.- Import that .fbx to a new scene. You'll notice the offset in some or all of the meshes (that don't happen on 2.79)

I have always used parent, "bone relative" without problems in blender 2.79 and prior
If I in 2.8 and above I use instead - parent "bone" (without "relative") I haven't had that issue with the offset in meshes.
Could be "bone relative" be automatically converted to "bone" before exporting to .fbx ?
