Everything I can find simply says to "cut/paste the link to the rack into the post editor", but that only creates a clickable link in my post rather than showing the actual rack in the post. I can't see anything I am doing wrong or any reason it should not work... what gives? What is the precise method/format of making this actually work? What the hell am I doing wrong????

This is the format I'm useing (that just yields a link):

Edit: Now that the bug is fixed, I added a space in the above link so that the link would show instead of the rack so what I was doing would be viewable.
