Attempt to create a repeatable MARC field (get or set). Notice you're
unable to.

1) Add a new order for an existing basket, with an existing record,
   visit:
/cgi-bin/koha/acqui/neworderempty.pl?booksellerid=1&basketno=1&biblionumber=76
2) Set the mandatory "Koha item type" for the item. Click the 'Add item'
   button below.
3) Notice the accounting details now have quantity:1
4) Set the mandatory "Fund" input in accounting details.
5) At the bottom, fill in all additional fields, click the '+New' and
   'Clear' links,  hit 'Save'
6) In the orders table shown, click "Modify". Notice all the fields are
   presented correctly in the edit form.
