Unable to resolve tests in monorepo with vitest.workspace.ts + root vitest.config.ts

[chriswheeldon-peakon]

Describe the bug

The plugin resolves no tests in a monorepo with a vitest.workspace.ts and root vitest.config.ts. I do not see any errors in the plugin logs.

I am using pre-release version 0.5.9 of the plugin.

Reproduction

The quickest way to reproduce is to add an empty or minimal (export default defineConfig({});) vitest.config.ts to the root of the monorepo-vitest-workspace sample (here).
