Some HTML files cause exception at attempt to create Workbook from them

Following simple HTML files without complex formatting or dynamic content cause strange exception at attempt to load them as Excel worksheet:
Samples.ZIP (1.2 KB)

Code sample:

var loadOptions = new HtmlLoadOptions(LoadFormat.Html);
var noteWb = new Workbook(htmlPathPath, loadOptions);

Exception message: “Item has already been added. Key in dictionary: ‘sub’ Key being added: ‘sub’”.
Stack:

at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add)
at .(String , ArrayList )
at .()
at .(Stream )
at .(String , Stream , LoadOptions )
at Aspose.Cells.Workbook.(String , LoadOptions )

As for me, there are no any places in them that could raise such error. Similar htmls are loaded without problem. Could you please explain what’s the problem?
