Weird introspection query

[Alexander Myltsev]

When I just load graphiql interface (same behaviour in incognito mode), it immediately sends introspection query:

For input query as follows:

query($name: String!) {
  nameResolver(names: [$name]) {
    total
  }
}

variables:
{
  "name": "Ctenidium molluscum var. compactum"
}

it sends query, and then in second that introspection query, that actually overlaps the result.
