Brief Rough Idle After Filling Up

Hello, I'm nearing 36k miles until the bumper-to-bumper warranty expires, and I will be setting an appointment for them to check a couple of things during my oil change. This just popped up in the past 2-3 weeks, and it has struck me as odd and worth mentioning to the dealer. But, looking to see if anyone else has had a similar issue.

To preface, I never top off. Once it clicks, I am done. I start the car and drive to exit the station, when I get to a red light and stop, I can feel the car has a slightly rough idle. I can even see it in the RPM gauge where the revs will go up/down a bit. It is very brief and lasts only for a few seconds. It never shuts off or throws a CEL. Once I take off and start driving, the car never does it again until it is time to fill up.
