//HACKYFIX: Daniel note: Very hacky workaround for an api issue
//Microsoft's api for getting item controls for the flipview item fail on the very first media selection change for some reason. Basically we ignore the
//first media selection changed event but spawn a thread to redo the ignored selection changed, hopefully allowing time for whatever is going on
//with the api to get things sorted out so we can call the "ContainerFromItem" function and actually get the control we need
