Loading node array with remote context fails?

Some statements are missing when doing the following:

```js
[
  { "@context": "http://schema.org" },
  { "@context": "http://schema.org" },
  // ...
  { "@context": "http://schema.org" }
]
```

but not in the following form:

```js
{
  "@context": "http://schema.org",
  "@graph": [
    {},
    {},
    // ...
    {}
  ]
}
```
