<p>Test passes if the box with a blue frame is identical to the orange one.
<div class="test">
<span>1 2 3 4 5 6 7 8 9 0 1 2 3456789012345678901234</span>

<!--
The ellipsis's width must be taken into account when balancing.
In this case, the ellipsis's width is 4 times the width of characters
inside the <span>.
The optimal balancing with the ellipsis is:
|---------------|
|1 2 3 4 5 6 7 |
|8 9 0 1 2.... |
|---------------|
The optimal balancing without the ellipsis would be:
|---------------|
|1 2 3 4 5 6 |
|7 8 9 0 1 2 |
|---------------|
