/**
* This is an especially interesting function. A naive reader might think that
* it returns this SmallVideo's "video" element. But it is much more exciting.
* It first finds this video's parent element using jquery, then uses a utility
* from lib-jitsi-meet to extract the video element from it (with two more
* jquery calls), and finally uses jquery again to encapsulate the video element
* in an array. This last step allows (some might prefer "forces") users of
* this function to access the video element via the 0th element of the returned
* array (after checking its length of course!).
