Multiple top-level queries do not work for unhealthy subgraphs

What is the current behavior?
This query:

{
  factories(first: 5, subgraphError:allow) {
    id
  }
  _meta(subgraphError:allow) {block {number}}
}

Returns:

{
  "data": {
    "_meta": {
      "block": {
        "number": 1001380
      }
    }
  },
  "errors": [
    {
      "message": "indexing_error"
    }
  ]
}

Which is missing the factories field. But if the _meta query is removed, the factories are returned.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
On a subgraph with non-fatal errors that is unhealthy, attempt to query more than one top-level field.

What is the expected behavior?
All top-level fields are included in the response.
