If I change my root tsconfig.json to this:

{
  "glint": {
    "environment": ["ember-loose", "ember-template-imports"]
  },
  "references": [
    { "path": "./config/tsconfig.src.json" },
    { "path": "./config/tsconfig.tests.json" },
    { "path": "./config/tsconfig.docs-app.json" },
    { "path": "./config/tsconfig.typedoc.json" },
  ]
}

I get different errors:
