I used to do that too, thinking there was some kind of bug. And then one day I got distracted by my toddler while rejecting and it turned out that yes, a few minutes later, the thing disappeared. So now I'm tempted to assume that if you don't wait then nothing guarantees that the partners got the message that you're not accepting their tracking. The only dark pattern in there, presumably, is that they're notifying partners serially rather than in parallel.
