NoEmptyLinesOpeningClosingBraces removes empty lines from body if functions start/end with comment

[andre-richter]

The following, when NoEmptyLinesOpeningClosingBraces is true,

func foo() {
  let x = 1

  // let y = 2
  // let z = 3
}

results in

func foo() {
  let x = 1
  // let y = 2
  // let z = 3
}

It also happens the other way around.

func foo() {
  // let w = 0

  let x = 1
}

becomes

func foo() {
  // let w = 0
  let x = 1
}

IMO both cases should be left unchanged, because these empty lines will likely be intentional. Also, in the stricter sense, they are not located after/before the opening/closing braces.
