Mixer button doesn't show correct status

Just a cosmetic bug: The “Show Mixer” button (F3) only changes its status from inactive to active and vice versa if the actual button is pressed, but not if one of the other methods of opening/closing the mixer window is used (closing the mixer window manually or pressing F3).

Yes, that’s a known issue. I think there’s a similar problem with the button status of the transport window. Also the VST Plugin windows.
