System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1060 3GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 445.87

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-03-12 05:06, hash: 375c7dc4ca
Worked: (optional)

Short description of error
When joining separate pre-painted GP strokes the weight of second stroke gets totally replaced by first one.

Exact steps for others to reproduce the error
Create a blank file
Create GP object, draw 2 squiggles and assign each to a separate vertex group image.png
(for the sake of experiment I duplicated that entire GP object)
now join those 2 strokes with Ctrl+J
all vertex painting is now ruined

Pardon my complete lack of git knowledge but how would I get a version of Blender with this fix applied?

@WOAS You don't need git, just download tomorrow the 2.90 daily build from here: https://builder.blender.org/download/

EDIT: The fix will be in the build of tomorrow or any date after the fix I did.
