The format needs to be on value, not on format, we just carry format around to be able to set it again at the end. value is the value that we care about and show a text field for.

This is easier and faster if not set when you have a if ($format) around the foreach.

Thanks, looks good now.

Changing status to possible backport.

It's not a priority on our side, but backporting this shouldn't be too hard and can be implemented in a very similar way in 7.x.
