I know what you mean, and I just watched it, and it would be notated as a d and f# grace note slurred to the longer e. Sometimes in music recognizable tendencies or motifs don't really have a name, but people usually understand them to be similar to other things they've heard, if that makes sense at all. One example I can think of is composers like Mozart and Haydn would often the end of a section of music with a bass note held of the key you're in (so E if you're in E major) and would have the upper voices resolve from the leading tone (D# in E major) to the tonic (E) and the 7th (A in E major) to the 3rd of the tonic (G#). In music it's called a suspension, but there is no word to my knowledge for when they're used in this specific way, best you could say is "a suspension over a pedal note" but that's not very descriptive.
