Minimizing to taskbar/toolbar used to be possible... has it been removed?

I get either really old topics. Or something not related. But I can't minimize the miniplayer to the taskbar anymore. Could have been ages ago since I used it the last time. But I want to listen radio now while I'm working and have a nice spot for it to be minimized. It used to minimize to the toolbar/taskbar. Now it still has a minimize option. But then it's still on the screen somewhere. And that's really annoying.

I have found a possibility for the icon to show in the bottom right. But I want the buttons, the previous button the play button and the forward button.

Please don't tell me that feature has been removed...
