When comparing the two attached documents in version 21.10, the comments present in right.docx lose their comment ranges, that is, they become “zero-width” comments at the end of the range they used to span.
Got it. I had misunderstood the section on the .NET release notes that refers to Java. I see that there are release notes for Java at Aspose.Words for Java 21.12 Release Notes that mention this issue. Thank you!
