Find All Refereences does not work across multi-root projects

[adampauls]

Type: Bug

Same issue as microsoft/vscode-cpptools#4711 but for Python.

Behaviour

I have a multiroot workspace for a Python mono repo. There is a root folder with project1 and project2 as subfolders. I have a multi-root workspace where all of ., project1, and project2 are included. I understand this to be the recommended usage, though there are complaints.

Expected vs. Actual

If a method is defined in project1 and used in project2, then Go to Definition works fine when inside project2, but Go to References in project1 only finds references in project1.

Steps to reproduce:

My .vscode/xxx.code-workspace file looks like:

{
	"folders": [
		{
			"path": ".."
		},
		{
			"path": "../project1"
		},
		{
			"path": "../project2"
		}
	],
