Moving a FLAC or WAV file on Wikimedia Commons to a new file name causes the player to disappear unless the file is re-uploaded.
Steps to reproduce:
1.) Go here: https://commons.wikimedia.org/wiki/File:Ugandan_national_anthem,_performed_by_the_U.S._Navy_Band.wav
2.) The file was recently moved; notice how the media player is not showing up in the usual spots as a result.
This happens on Microsoft Edge, Internet Explorer, and Google Chrome and in Incognito Mode as well.
