Repro Code

interface ObjectWithFunction {
  func: (x: number) => number
}

const objAsVariable: ObjectWithFunction = {
  func: x => x + 1
}

const arrAsVariable: ObjectWithFunction[] = [
  {
    func: x => x + 1
  }
]

class Example {
  objAsField: ObjectWithFunction = {
    func: x => x + 1
  }

  // all of the above work as expected

  arrAsField: ObjectWithFunction[] = [
    {
      // this should be allowed
      func: x => x + 1
    }
  ]
}

Additional Info

I would have liked to check on which version this started occurring, but the online playground apparently doesn't support selecting the tseslint version.
