| <!-- |
| Both column boxes of div#inner start in the 1st |
| column box of div#outer multi-column element. |
| The first 3 lines boxes of 1st |
| column box of div#inner will be rendered inside the |
| 1st column box of div#outer but not its 2nd. |
| Because 1st column box of div#outer is |
| 6em wide while the div#inner multi-column element |
| is 14em wide, this makes the first 3 line boxes |
| (with the 'z' trios) of 2nd column box of div#inner |
| clipped. |
| |
| Then, at this point, the div#inner multi-column |
| element should be fragmented in order to continue to |
| render the 5 empty line boxes it has into the |
| 2nd column box of div#outer. Since those 5 line |
| boxes are empty, we only see the extension it |
| creates horizontally, which is |
| 14em - 6em == 8em horizontally and |
| 5 lines boxes == 5em tall |
| |
| |
| Expected results: |
| |
| 0em 14em 22em |
