v18 - Player.Art(foo) is empty when playing music from outside Music window

As the title says... Player.Art(thumb) &  Player.Art(fanart) are empty when you start playing music from anywhere else (eg home widgets) except "Music" window. The same issue if you try to PlayMedia($INFO[ListItem.FilenameAndPath]) from inside the MusicInformation window.

Checked with several skins including Estuary and all have the same behavior.

Kodi 18.5
Wndows 10
