Green window expand button broken on Mac

On Mac version 7.0.1

Set a window to ‘Always On Top’ - e.g. MixConsole
Click the Green ‘Expand Window’ button (Top LH corner of window traffic light buttons).
The window doesn’t expand as it should, it closes as if you’d hit the red button instead.

The buttons work fine when ‘Always On Top’ isn’t used.

Can we please have ‘Always On Top’ for the Pool?
