Shuffle/ Random play on playbar does not reset to off when playbar closed with stop

[Vicpa]

This has been around for a long time, just forgot to add it to list. If shuffle is selected on playbar. Expected behavior would be it would reset to off. When that playlist was closed by clicking the close button.
