Can't edit description field on a price set option

You can create a price option with the selection being a radio button (it probably is an issue with options set for price fields of a checkbox too) and have the opportunity when initially creating the price field options to indicate a label and a description, but it then becomes impossible to ever edit or delete that description again. The description field is not displayed when you return to edit that particular option for a price field.

You can see this in the 3.3 sandbox at http://sandbox.civicrm.org/civicrm/admin/price/field/option?reset=1&action=update&oid=1&fid=1&sid=1. This particular field option has a description but no option is given to edit it.
