Research direction

Start by reproducing the cascader issue from the linked Element UI demo using element-ui 2.15.14, with multiple selection enabled and the deepest level expanded. Trace the cascader component behavior for the final-level checkbox and verify the fix by confirming that the last-level option can be selected.
