Short description of error
Grease pencil drawings are not visible when contained in a collection that is instanced in a foreign scene.

Exact steps for others to reproduce the error

Create a new '2D animation' file.
Draw a grease pencil stroke in the selected GP object (inside the collection named "Collection")
Create a new scene.
In the new scene: Object Mode, Add > Collection Instance > Collection.
The collection instance is added but the stroke isn't visible in the new scene (I expected that it would be).

Possibly related. Blender crashes if I then do the following:

Save the .blend file described above.
Open a new file (2D animation)
File > Link > (select to the "Collection" item inside the saved .blend file's Collection group, and click 'link from library')
Blender crashes

This crash is a different issue. The object not visible is due a different reason...I'm thinking how to fix it.
