[nvda] Re: Automatic reading of webpages

Yes, I've had numerous messing about with forms and petitions sites where it goes back to the very top when it really should have put you at the start of the info you put in to check it etc. I just do not know if this is in fact what sighted people get, but because they can see the whole thing, they do not have to worry about a specific focus or start.

A screen-reader should not return to a visited link.  It should return

and stop at the beginning of a sentence, that is where you should be
returned.

Just to provide some info on this:
Note that a link or button is normally the way of "leaving" an article.
I'm not even certain that a web browser visually returns to the exact
position to which the user scrolled if not returning after following a
link. If it does, it should also fire the appropriate events for
assistive technologies.

A screen reader can try to track this information, but I see two
problems with this:
1. The state will be lost when the screen reader is restarted. This
doesn't make sense if the browser is visually returning to the correct
position.
2. If we track the information by URL, inaccuracy and unreliability can
occur. Many pages can have the same URL with different post data. In
addition, the page might have mutated by the time the user returns, in
which case the remembered position will be incorrect.
This is why I'd much prefer to try to get this information from the
browser. The problem is that there seems to be alot of flakiness in this
regard in browsers.
