Bug when last panel has a minSize

[T0miii]

Currently there is a bug when the last Pane has a min-size.
After reaching the threshold the pane will jump to a random position and removed the calculated sizes from the other panes.

  <splitpanes class="default-theme"  style="height: 400px">
    <pane >
      <span>1</span>
    </pane>
    <pane>
      <span>2</span>
    </pane>
    <pane max-size="70" min-size="20">
      <span>3</span>
    </pane>
  </splitpanes>
