When using `if` and `loop` together, the `if` only seems to apply to the first iteration.

I would expect that the below would result in the step test not being run, but seemingly it runs.

mod "local" {
  title = "if-loop"
}

pipeline "test" {

  param "messages" {
    type = list(string)
    default = ["a", "b", "c"]
  }

  step "message" "test" {
    notifier = notifier["default"]
    if = false
    loop {
      until = loop.index == length(param.messages)-1
    }
    text = param.messages[loop.index]
  }
}

Output:
