Actually Opera was first: [url][visit link][/url]. WebKit, however, had the first publicly available engine to get 100/100 ([url][visit link][/url]), though Opera followed shortly thereafter: [url][visit link][/url]. Also, note that a) WebKit [i]didn't actually pass the test, just got 100/100[/i] in their first posting, and Opera [i]originally passed an incorrect test[/i], so they didn't exactly pass it in spirit, even if the did by the letter, when they first reported their score (by the time they made their public build available, though, the test had been fixed and so had the bug in Opera that gave it 100/100 even though the test was wrong).
