For quite some time now, I have on occasions had problems with VoiceOver focus not moving to the front tab in Safari after switching between tabs.
On these occasions, VoiceOver will behave as if the tab I just left is still the front tab - in that it will speak the contents of tab X when navigating even though tab Y is definitely the front tab. No amount of switching between tabs will flush this behavior when present. I typically have to close one or more tabs - or quit and restart Safari itself - for VoiceOver to bet back to working as expected.
It's all very odd and also all very frustrating.
Is anybody else also encountering this?
