Reappearance steps (重现步骤)

1. Open the example link in the doc of Descriptions https://codesandbox.io/s/j639kx
2. remove the previous 6 n-descriptions-item
3. save changes
4. then you will find the span does not work

Expected results (期望的结果)

span will work even if the items only occupy one line/row

Actual results (实际的结果)

span will never work in the first line/row

Remarks (补充说明)

如这个链接里的示例 https://codesandbox.io/s/loving-robinson-uostjy
即使设置了全部 items 的 span，占据第1行的 items 的 span 都不会生效，大于第1行的才有效
