Fix: Set title for multiple youtube video player with the same ID  (don't rely on id to set title)

When an identical youtube video is embedded multiple times on the same page. 
it will only be successful setting title to 1st element in the dom matching a unique id which is based on the actual youtube video id.
var are you?
