ctx.db.request returning null when the first response attribute is null

[TGNThump]

ctx.db.request(query, {identifier}).then(data => console.log(data));

prints the following to the console

Request to https://[REDACTED]:4466/lsalpha/dev:
query:
query getUser($identifier: String!) {
  user(where: {slug: $identifier}) {
    ...selection
  }
  email(where: {address: $identifier}) {
    user {
      ...selection
    }
  }
}

fragment passThrough on User {
  name
  email {
    address
  }
}

fragment selection on User {
  id
  password
  email {
    isVerified
  }
  ...passThrough
}
operationName: getUser
variables:
{
  "identifier": "[REDACTED]"
}

Response from https://[REDACTED]:4466/[REDACTED]/dev:
{
  "user": null,
  "email": {
    "user": {
      "id": "cjkkzloq300zb0818r2s2lkk2",
      "password": "[REDACTED]",
      "email": {
        "isVerified": false,
        "address": "[REDACTED]"
      },
      "name": "[REDACTED]"
    }
  }
}

null

Is this the intended functionality, and if so, how would I get access to the email argument returned by the query?
