Problem with viewing metaballs in group instance even though it is assigned to that group
Open, Needs Triage by DeveloperPublic

Description

System Information
Operating system: Windows 10
Graphics card: AMD FirePro SDI (0x6861)

Blender Version
Broken: 2.79 and 2.8

I created a particle system, with metaballs as my object. I then added this particle system and a few other objects to a group. When I add a new instance of that group, the metaballs are not visible in the instance. I am still able to replicate this issue without the particle system as a factor.

Steps
-Add metaball to scene
-Assign to a group
-Create a group instance of that group
-You will notice that you can not view the metaball

This is a followup of a Blender Stack Exchange question and probably a dupe of

https://developer.blender.org/T21747 and https://developer.blender.org/T69753

Note that this doesn't currently work in 2.79 either, I can recreate it in Windows 7 64bits and Windows 10 64Bits.
Converting metaballs to mesh seems to work around the issue, although in 2.79 the object gets removed from the group, and requires manually adding back.
