Bdi Element Expected

From WebKit bug 50913

In this example, usernames are shown along with the number of posts that the user has submitted. If the bdi element were not used, the username of the Arabic user would end up confusing the text (the bidirectional algorithm would put the colon and the number "3" next to the word "User" rather than next to the word "posts").

• User jcranmer: 12 posts.
• User hober: 5 posts.
• User إيان: 3 posts.
