Auto-hide dock causes clock/notification to move

When disabling / enabling hiding of the dock - or indeed changing the width of the dock - in system settings - the clock / notification area moves. These feels wrong. The clock is not related to the dock size, and should not move with it. The clock should be in the centre of the display, not the centre of the usable area of the desktop I believe.

Steps to reproduce

Open system settings
Select dock
change the toggle to auto-hide the dock
Observe the clock move with the toggle

Expected behaviour

Clock/notification are is locked to the middle of the screen.
