File & Media webpart: Powerpoint first slide links aren't clickable

Looking to see if anyone else has this experience/any solutions:

You add a File & Media webpart to a SPOnline page, link it to a PowerPoint file. The first slide has a hyperlink, but that link isn't clickable when the page first loads.

If you move to another slide, links work correctly, including when you move back to the first slide.

Any way to get this functionality to work correctly with the File & Media webpart?

Slides work fine when you open in PPT, no amount of recreating the PowerPoint works, but switching to the "Embed" webpart solves the problem.
