It's because the core queries the screen dimensions before it reads the screen 
content. The two operations are entirely separate.

I'm guessing here because I know the path in the core is very short. My guess 
is that the speech driver and/or synthesizer may have a somewhat expensive path 
for getting the synthesis started.

The short answer is that it's never been addressed for at least two reasons. 
One is that this is the first time we've had a dynamically growing screen 
width. The other is that it's not noticeable to a braille user. A possible 
third reason is that I myself don't use speech so I end up only ever reacting 
to speech issues which others take the time to bring to my attention.

In any event, I now have an idea as to how to fix the problem without changing 
the menu pseudo-screen code. I should be committing a potential fix fairly 
soon.
