Location dropdown on Add Node does not sort/filter

When adding a node via the UI to an existing Provisioning Requisition, the Minion Location dropdown does not sort the list or filter when typing a few characters of the location name. It does highlight matching locations, but the location dropdown on the Node Search page filters when typing.
