Spacetree: Zooming broken (or breaks the visualization on zoom event)

[gatapia]

Even with very simple settings zooming breaks the visualisation.

var opts = {'injectInto': this.panel.id, 'Navigation': {'enable': true,'zooming': 10 }};

Hmmm where is my attach file button?? Anyways, its very straight forward to reproduce so I shouldn't need to attach an item.

Thanks
