Playground does not give expected result for expansion test c037

Hi,

from expansion algorithm, I don't understand how nesting is supposed to work, especially when step 14.2.2 specifies to "Recursively repeat steps 13 and 14 using nested value for element", but steps 13 and 14 do not modify the active context, so nested values are expanded using the current active context, not the context associated to the nesting key.

I must precise that I'm implementing in a functional language, and it it not clear to me from the wording of the algorithm if active context is passed by reference along recursive calls. By now I assume that it is not the case but I way be wrong. It may be useful to indicate for each algorithm which arguments are passed by rerefence.

Well,in fact it seems that either expansion test c037 is wrong, or jsonld.js implementation is wrong.

Input of c037 is

{
  "@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 of c037 output is:

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

But JSON-LD Playground expands input to:

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

My implementation gives the same result as the playground, but this is not the expected result. Who is right ?

Same for expansion test c038.

Might be an issue for jsonld.js. @davidlehn?

Looks like those tests are not passing in jsonld.js right now and are currently marked to be skipped. I don't recall the specific reasons why. Needs someone to look into what the fix should be.
