<!-- Notes:
The test creates a box with room for 6 characters, causing wrapping to occur either between the 6th and the 7th character, or before the 6th if the breaks after the 6th or before the 7th are prohibited.

It also creates the expected behaviour with a ref instance, using <br/>. Each line ends with a span. The test then checks whether the left edge of the span is in the same place in test and ref instance.
