menu not aligned in opera?

[svl]

I should not have used the word "wrong". Of course in browser land there are a lot of differences and who is "right" is difficult to determine and sometimes simply an opinion... But I'd still like to know what reason/rules/bugs/etc caused Opera to be different than eg Firefox in this specific case, where it causes a theme to render wrong. After all, there are standards/definitions for the manufacturers to use, so an answer could be "Opera is ahead of the rest in terms of standards", or "Opera is doing this because.....a known "issue".... ".
