Allowlist Bug: including an unused fragment results in whole query being blocked (2.0.0 alpha v6)?

[kennandavison]

Hi, I have an allowlist operation that looks like:

query exampleQuery($where: a_bool_exp!) {
  a(where: $where) {
    ...frag
    b {
      id 
    }
  }
}

fragment frag on a {
  id
}

When I include a fragment for b, it seems to get blocked even if I'm not using it:

query exampleQuery($where: a_bool_exp!) {
  a(where: $where) {
    ...frag
    b {
      id
    }
  }
}

fragment frag on a {
  id
}
fragment frag2 on b {
  id
}

Exact same fields. The mere insertion of the fragment without even using it seems to get the whole query blocked. Any idea? Literally just this 1 query of 100+.

Not sure if this related: #5156

I think allow list engine does a blind string match of the incoming query and hence an extra fragment throws an error.
