Background color not converted from HTML to RTF

Hello, I am testing the conversion from RTF to HTML and back to RTF. Everything seems fine, I have only found one problem: When converting from HTML to RTF, the backgsound color of a text is lost.
You can see an example in the attached file ‘background-color-error.png’: the column on the left contains the original RTF text, the large column on the right contains the HTML converted from the original RTF, and the column in the center contains the RTF converted back from the HTML. As you can see, the gray background color is gone (this happens with other examples too). Here is the code (C#) I use to convert from HTML to RTF:

public static string ToRtfTest(this Document document)
using (var memoryStream = new MemoryStream())
var saveOptions = new Aspose.Words.Saving.RtfSaveOptions();
saveOptions.ExportImagesForOldReaders = false;

document.Save(memoryStream, saveOptions);
var rtf = new StringBuilder(Encoding.Default.GetString(memoryStream.ToArray()));
return rtf.ToString();

I am also attaching the original RTF and the converted HTML.
I have gone through the save options but have found nothing, nor on the internet or the forum.
Am I missing something or is this a bug? In this case, can it be fixed?
Thank you
