formatter removes indention of first comment in for block

The intended formatting:

object Foo {
  for {
    // take first
    fst <- Some(4)
    // take second
    snd <- Some(2)
  } println(s"${fst}${snd}")
}

After using the auto formatter:

object Foo {
  for {
  // take first
    fst <- Some(4)
    // take second
    snd <- Some(2)
  } println(s"${fst}${snd}")
}

Bug or feature or configurable?
