Self-voicing should read modal screens on top and not read ones on the bottom

[qirien]

During self-voicing mode, when there is a screen on top of another screen (often a modal screen), it reads the bottom screen first. I would expect that it would not read the bottom screen at all since the top screen is modal and you can't select anything from the bottom screen.
