<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Media: When reusing the initial values from the global MediaElement config object, the config object should first be cloned. Objects in JS are references that will retain any changes. This fixes an issue where player controls could get mixed up between instances when multiple players (namely, single audio and audio playlists, in a certain order) are on the same page.
Props Fab1en.
