i have the same problem when dialog is closed=true.
when dialog height property is undefined, v1.3.6 will be auto size the height when dialog shown
see the code bellow, if
closed:true the dialog cannot auto height when it is shown
<div style="margin:20px 0;">
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="$('#dlg').dialog('open')">Open</a>
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="$('#dlg').dialog('close')">Close</a>
</div>
<div id="dlg" class="easyui-dialog" title="Basic Dialog" data-options="iconCls:'icon-save', closed:true" style="width:400px;padding:10px">
