I found what appears to be a new bug in Safari 7.1 and VoiceOver, running under the latest version of Mavericks.
When I press Command-Left Bracket to go back one page, one of two things will happen. Either I end up with an empty scroll area, or VoiceOver will continue to announce elements from the webpage I just left. The correct page is displayed on screen, but VoiceOver is not aware of it. I have to press Command-R to reload the page before VoiceOver operates correctly.
Has anyone else noticed this annoying behavior?
