`expand-manifest.jsonld#tc037` mismatches the Playground

[anatoly-scherbakov]

Manifest

jq '.sequence[] | select(."@id" == "#tc037")' tests/expand-manifest.jsonld

which gives:

{
  "@id": "#tc037",
  "@type": [
    "jld:PositiveEvaluationTest",
    "jld:ExpandTest"
  ],
  "name": "property-scoped contexts which are alias of @nest",
  "purpose": "Nesting terms may have property-scoped contexts defined.",
  "input": "expand/c037-in.jsonld",
  "expect": "expand/c037-out.jsonld",
  "option": {
    "specVersion": "json-ld-1.1"
  }
}

Input

cat tests/$(jq -r '.sequence[] | select(."@id" == "#tc037") | .input' tests/expand-manifest.jsonld) | jq

that gives

{
  "@context": {
    "@version": 1.1,
    "@vocab": "http://example.org/",
    "nest": {
      "@id": "@nest",
      "@context": {
        "@vocab": "http://example.org/nest/"
      }
    }
  },
  "nest": {
    "property": "should be in /nest"
  }
}

Expected output

cat tests/$(jq -r '.sequence[] | select(."@id" == "#tc037") | .expect' tests/expand-manifest.jsonld) | jq

which gives

[
  {
    "http://example.org/nest/property": [
      {
        "@value": "should be in /nest"
      }
    ]
  }
]

What about the JSON-LD Playground?

[
  {
    "http://example.org/property": [
      {
        "@value": "should be in /nest"
      }
    ]
  }
]

Difference

+    "http://example.org/nest/property": [
-    "http://example.org/property": [

Question

My understanding of @nest logic is insufficient to judge who's right here. Any thoughts?
