Default Video with Alpha Channel not transparent

Mac 10.15.7
Microsoft 365 16.48
PowerPoint issue

I have created a video with a transparent background. It's a 5 second .mov file. I confirm this in Adobe and ScreenFlow video editors, and with Keynote, all on Mac. However with PowerPoint, there are issues.

One good point, when I place the .mov on a page, and play it from the controls at the bottom of the page, it plays as expected, with a transparent background.

When I click on the play button in the Animations Pane, it's not transparent, rather has a black background. The same is true for Slide Show.

Any thoughts?
