I would like multiple citations to be sorted with respect to the order that they appear in the references, no matter the order in which I write them.

Please see the following MWE. It produces 

> 
> First: [1,2] Second: **[2,1]**
> 
> 
> 

whereas I would like it to produce:

> 
> First: [1,2] Second: **[1,2]**
> 
> 
> 

with the same code.
