Hyperlinks / Action Commands Break after Loading and Saving a Presentation in C#

Hi there,

after loading and saving a presentation with Aspose.Slides.NET@23.8.0, some hyperlinks and specifically action buttons break. Depending on the type of ppaction, this can result in the action not being usable or the entire presentation being corrupted and unrepairable by PowerPoint.

In the case of ppaction://media (used for video playback) we have been able to narrow the crash down to a single missing attribute in the slides’ OOXML.

Before:

<a:hlinkClick r:id="" action="ppaction://media"/>

After:

<a:hlinkClick action="ppaction://media"/>

It seems as though PowerPoint cares about the r:id attribute even if it’s empty. Is there any chance this could be investigated?

Have a good day and thank you very much!
