Title: jquery.com: Fix broken selector for try-jquery hidpi image

Follows-up fefb5a7a30eb3ea148d08652af6336ee6f30cf4e.

The selector was broken, and that was actually a good thing
since there was no background-size rule so the image would've
just be shown twice as big and cropped to the same 126x277px box.
