requireing confirmation for the multi-part confirmation added in this
bug.

Test plan

2/ Checkot an item with attached materials
3/ Navigate to a page that display your users issues table (the checkout
page is a reasonable example)
4/ You should have the option to select items for return in the table
(If not, use the column settings to enable the feature)
5/ Select at least the item with attached materials to return
6/ Upon clicking the return buttton you should find that items without
additional materials are returned as expected, but rows with additional
materials turn yellow and contain a message and additional checkbox for
confirmation in the table.
7/ Ensure the checkbox is selected and click the return button again
8/ This item should have been returned.
