Ins/del tags missing on equations when converting docx to html

We are using Aspose.Words for .NET 16.8 to create diffs between docx files and to convert those diffs to html.
Find attached two documents and the diff between them, created with Document.compare and Document.save. diff.docx show that an equation was added, but diff.html lacks the ins/del tags on the image representing the equation.
