`opus' header field at surprising position

[Werner LEMBERG]

Folks,


consider this snippet (image attached):

  \header {
    title = "title"
    opus = "opus"
    composer = "composer"
    copyright = ""
    footer = ""
    tagline = ""
  }

  \markup { top1 }
  \markup { top2 }
  \markup { top3 }

  \score { c''1 }

I would expect that `opus' appears vertically before `top1'.

Is this a bug?  Otherwise, I suggest to change the code so that the
header block really stays together.
