Gridmap does not display all children of a tile

[furkanoeztuerk]

Godot version:
v3.2.2.stable.official

OS/device including version:
Windows 10

Issue description:
The gridmap does not display all children of a tile. Only the first meshinstance is displayed, the rest is ignored.
Here is how the tiles scene looks:

There is one parent node, with two meshinstance children. The first child is a sphere, the second child a cube.

Here is how they look when used in a gridmap:

Notice how only the first meshinstance (sphere) is displayed.

Steps to reproduce:

1. Create tilemaps
2. Convert tilemap scene to meshlibrary
3. Use meshlibrary in gridmap

Each item im the library only contains one Mesh, this is intended. Should be part of the associated tutorial no?

Yeah, the tutorial doesn't really clarify it. It just tells you to download the demo and doesn't even show the basic meshlib tree. I'll transfer it to Godot docs, because it's intended behavior.

Also the Parent node is unnecessary. Your meshes should be directly under root.
