LibreOffice Impress video loop does not work in newest version 5.3.7

I just tried to embed a video in LibreOffice Impress 5.3.7 and run it in a continuous loop. This does not work. However, I have successfully tested this with the same video in LibreOffice Impress

Why does this feature not work in LibreOffice 5.3.7 anymore?

I still have the same problem with on Win 7. Because of this bug, I stick to on my notebook for presentations.

The question is also at Video looping in Impress not working, although still unresolved. (Note: My original comment is no longer accurate, and the link goes nowhere. If anyone else can delete the comment, I would be grateful.)
