I didn’t use the word “leading” or imply they were… I’m happy that Safari, who have been at times been criticised for not keeping up, are on this occasion helping to push web standards forward. That has nothing to do with who was “first”, but in this case they happen to have been. If they were two weeks behind I would have made the same comment on a thread about a blog post on their own blog.
