full-cover is truncated with some media_player entries

[rh8056]

I'm using a universal media player to combine a few different media players from an Amplipi. In the following screenshot, all of the mini-media-player entries are set to full-cover. You can see that amplipi_source_1 shows a full cover. When I look at the attributes of the media_players and pull out the entity_picture, if I paste that into a web browser, every picture is the same and none are truncated.

I'm not sure how to help investigate, but if I open up web inspector in Safari, all three images are the same (full sized)
