Fix usage of MediaElement in CarouselView/CollectionView, etc.

[jfversluis]

Description of Change

The MediaElement transport controls keep giving issues in some cases. I think regular pages vs Shell now works well, however looking at #929 there are still issues when using it in a CarouselView. This PR should fix that.
