Foreign object filter part of an _or set of filters doesn't seem to do anything

[fredcarle]

With a query of the form:

query {
  Book (filter: {_or: [
    {title: {_ilike: "%Test3%"}},
    {author: {name: {_ilike: "%Test3%"}}},
    {subTitle: {_ilike: "%Test3%"}}
  ]}) {
    title
  }
}

The {author: {name: {_ilike: "%Test3%"}}} part of the filter doesn't seem to have any impact on the result. It seems like having this object filter inside an _or set doesn't work. The following does work however.

query {
  Book (filter: {author: {name: {_ilike: "%Test3%"}}}) {
    title
  }
}
