Several browsers (Firefox 3.6.13, Konqueror 4.6) will fail this testcase
because 1ex is first computed and then rounded and because font-size of
element is not a multiple of 5

.seven {letter-spacing: 1.25ex;}. 24px mult 0.8 == 19.2px rounded down
by Konqueror 4.6 but rounded up by Firefox 3.6.13. Then, 19px mult 1.25
== 23.75 rounded down again by Konqueror 4.6 while 20px mult 1.25 ==
25px by Firefox 3.6.13.

Solution is to use font-size: 20px or 30px
