Hello,

Following the upgrade from 1.10 to 1.11 $.sub fails to work properly. You can observe this issue here:

http://jsfiddle.net/07va5veg/ - correct behaviour with 1.10 - b function is successfully set on instance a of jquery and is used down the chain

http://jsfiddle.net/07va5veg/2/ - incorrect behaviour with 1.11 - while b function is successfully set on instance a of jquery, it appears that calls down the chain target original jquery object
