The dock peek preview pop-up can remain on the screen even after the target app is a closed from the dock. In the attached video, Firefox is quit, however the preview pop-up remains on screen. Presumably this is happening because the mouse pointer is hovering over the preview window, keeping it on screen until the preview is clicked or the pointer is moved away.
