We are using Aspose.Words for .NET 18.12 to convert docx files to html.
The attached zip file contains example.docx, which contains a hyperlink with a tooltip (called Quickinfo in Word). If the docx is saved as html using word, the tooltip is present in the html (see example_Word_SaveAs_HTML.html).
If we use aspose to convert the docx to html, the tooltip is missing (see example.html).
To reproduce example.html, build the VisualStudio solution (DocToHtml.sln) and execute Tester.bat.
Thanks for your inquiry. We have tested the scenario and have managed to reproduce the same issue at our side. For the sake of correction, we have logged this problem in our issue tracking system as WORDSNET-17871 . You will be notified via this forum thread once this issue is resolved.
