Does not render CustomXmlPart inserted by Chem4Word

[MikeWilliams-UK]

Using Chem4Word insert a chemical structure (Chem4Word is at https://github.com/Chem4Word/Version3-2) Save the document and close word. Open the document using OpenXmlFileViewer Click on item1.xml in the tree view

The xml for the inserted chemistry is not displayed correctly in the read tab

The xml is shown correctly in the Edit tab

At this moment I am not sure if Chem4Word or OpenXmlFileViewer is at fault
