Mine does it also. Doesn’t register on the RPMs though. Drive it and it goes away. Also does it if I leave the engine running and fill up. Makes me think it is a vacuum leak down or something. Nothing I am concerned about.
One of the guys at ford thought it was the same thing, a vacuum leak. Hard to find, but nothing will hurt it

Mine will do the same thing when cold and sitting a few days. Goes away pretty quickly, like 10 seconds and is very slight but I notice everything..
