  <div id="min-sized-parent">

    <div class="test-overlapping-green">A   </div>

    <div class="test-overlapping-green"> G  </div>

    <div class="test-overlapping-green">  M </div>

    <div class="test-overlapping-green" id="last">   Z</div>

  </div>

  <!--

  The 3 white spaces following or preceding
  the "A", "G", "M" and "Z" do not
  get wrapped. That is by definition of
  'white-space: pre'.

  Since the div.test-overlapping-green
  are floated and since their parent in
  the flow is 0-width, then these floats
  are min-content sized.
