This looks like an old bug, please refer to Add a draggable item to tree will cause js error

As a workaround, you can try the sample below:

<zk xmlns:w="client">
    <script><![CDATA[
        zk.afterLoad("zul.sel", function () {
            var _tiWgt = {};
            zk.override(zul.sel.Treeitem.prototype, _tiWgt, {
                initDrag_: function () {
                    if (zk(this.$n()).isRealVisible()) {
                        _tiWgt.initDrag_.apply(this, arguments);
                    }
                }
            });
        });
    ]]></script>
    <window>
        <tree multiple="true" checkmark="true" mold="paging" pageSize="2">
            <treecols>
                <treecol label="Test"/>
                <treecol label="Test"/>
                <treecol label="Test"/>
                <treecol label="Test"/>
            </treecols>
            <treechildren>
                <!-- the draggable attribute cause error while page changed -->
                <treeitem draggable="true" label="Test" />
                <treeitem draggable="true" label="Test" />
                <treeitem draggable="true" label="Test" />
                <treeitem draggable="true" label="Test" />
            </treechildren>
        </tree>
    </window>
</zk>
