A span with 2 new lines after it and then some bold text only shows 1 new line, adding additional new lines does not change the appearance.

Reproducible: Always

Steps to Reproduce:
1. apply white-space:pre-line; to a div
2. put a span within that div
3. put 2 new lines after the span, and then <b>text</b>
Actual Results:  
one new line shows

Expected Results:  
two new lines should show

Happens in every version of FF I tried, 3.5, 3.6 and 4.0 beta.
