System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Radeon RX 590 Series ATI Technologies Inc. 4.5.14742 Core Profile Context 21.8.2 27.20.22025.1006

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-10-17 17:10, hash: 452c78757f
Worked: (newest version of Blender that worked as expected)

Short description of error
If i bind Grease Pencil to the Armature without Vertex Groups (not Empty) and when i start to weight paint then Vertex Group is created with the name Group instead of the name same as the selected bone.
And the bone does not affect the vertices of the stroke until I manually rename the group according to the name of the bone. For polygonal meshes this feature works
This problem does not extend to Armature Deform With Automatic Weights.

Exact steps for others to reproduce the error

  1. Select Grease Pencil object and Shift+ select Armature -> Ctrl+P Armature Deform (not With Empty Groups and not With Automatic Weights)
  2. Select Armature and Shift + select Grease Pencil object -> switch to Weight Paint Mode
  3. Weight painting
    [Based on the default startup or an attached .blend file (as simple as possible)]
