I didn't notice it when I had the 2017 Macbook, but both my Macbook Air and MBP 2015 has the same issue. Why hasnt Apple solve this after all these years?

Edit, I am using it with the UK plug, unsure how this is a grounding issue.

I'm pretty sure the UK MacBook charger plug is not grounded. It has the ground pin, of course (UK sockets won't accept a plug without it), but there's only the standard 2 wires going from the detachable plug to the main body of the charger.
