Tree with checkmarks shows layout quirks

Tree with checkmarks, where not all items are checkable='true', show strange item icon positions and 'squashed' text layout in ZK 3.5.1

This can be fixed in Firefox 3 and Chrome as follows:

<style>
div.z-tree-cell-cnt input { float: left }
span.checkmark-spacer { padding-right: 2px; }
</style>

IE6, as always, is a special case and needs:

<style>
div.z-tree-cell-cnt input { float: left }
span.checkmark-spacer { padding-right: 5px; }
</style>
