When using the "Open Immediately" feature this is fine, but when waiting and opening from the drop down dialog, the TinyURL suffers from an internal redirect.

TinyURL: http://tinyurl.com/dbyrnz
URL produced from "Open Immediately": http://63.134.213.17/_media/imgs/arti... (correct)
URL produced from waiting and clicking "Open": http://tinyurl.com/http://63.134.213.... (incorrect)

This is totally reproducible for me.
