GraphQL ignores section filter if section handle does not exist

Description

When running a query filtering for a section handle that does not exist, Craft returns all entries instead of null. This behavior seems to only apply to the section. Filtering for a non-existing slug returns null entries.

Additionally, it also works just fine when we add any other filter to the query.
For example page: entry(section: "i_dont_exist", siteId: "1") returns null.

Steps to reproduce

1. Create a query for a section that does not exist.

query PageData {
  page: entry(section: "i_dont_exist") {
    id
  }
}

2. Check that result contains an entry.

{
  "data": {
    "page": {
      "id": "2632"
    }
  }
}
