One of CreateBR is still virtual method, but it is unnecessary to use it. So we should remove virtual keyword and remove override method. Also, we should move native dom version of CreateBR to TextEditor to use it on TextEdtitor. MozReview-Commit-ID: GCazJtY4urV --HG-- extra : rebase_source : 8e0d71631f0070a928bc0f4817dd6efe7c833f1b
