Just had this on my phone. Was playing a game that involved a bunch of tapping, and some system message (I have no idea what) popped up and was immediately dismissed (or confirmed!) as I happened to come down on one of its buttons at that exact instant. Seems so obvious that these things shouldn't become active until a few hundred ms after they appear.
