Add clone from created presentation not including all fonts

Hello Team,

We are currently evaluating Aspose.PDF and Aspose.Slides from converting PPTX to HTML and back to PPTX.
We have an issue with fonts being removed when we are creating a new presentation from slides of a presentation that we created with Aspose.

We have a pptx file that we export to HTML using Aspose PDF and Slides. We make changes to the html using a Rich Text Editor, and we convert the HTML to PPTX using Aspose.PDF.

The problem appears on the next step we do: we import the resulted PPTX file into a new Presentation, and add a clone to the original PPTX presentation. The problem is that the cloned slide does not contain all the fonts.

Attached is an archive containing the Original PPTX file, and the source code we use for converting HTML to pptx.
