Throttle hanging/sticking?

So I've had this happen a couple times on my Evora GT, and, as the first car I've owned with a supercharger, I was wondering what the solution might be.

When I am rolling and shift our of gear to give the car a little throttle blip (admittedly most times for the joy of small kids who are looking at the car!), I sometimes have the throttle hang open so that instead of a quick rev and jump to 4k or so, it will stay revved up to that amount for a good 2-3 seconds, which of course shouldn't happen, and totally defeats the purpose of revving for the kids!

Is this a possible characteristic of something sticking on the supercharger, likely electronic, or what? The pedal is returning to normal for what it's worth. I've yet to drive the car really hard yet as I'm not quite through break-in, but this has happened a few times while driving too and it's a bit disconcerting. Any help is greatly appreciated as I'll likely have it in for first service in the next 30-45 days, weather permitting.

Come to think of it, I probably had just depressed the clutch in order to rev the engine a little bit, so I'll have to try this out by moving into neutral completely and seeing if I get the same behavior. That video was actually very helpful, and I guess I didn't realize that all of my stick shift vehicles prior likely had a manual throttle rather than electronic. Thanks!
