It looks like [loop-code] returns the first return_field in the list. 
I thought [loop-code] always returned the code/key, and I think that's
how it worked ~5.0.  I guess it's more like a change in functionality
than a bug.  In case not:

[loop search="ml=1/st=db/rf=title/ra=1"]
[loop-code]
[/loop]
