A decent screen reader will look at the final rendered Dom and obviously cull items off-screen, the same colour as the background, or 1px high.

If it doesn't, its a bug in the screen reader.

There's quite clear standards on how screen readers are expected to interact with the DOM. What you claim is in none of them, and the techniques you mention are explicitly mentioned as something authors of webpages should avoid/mark up correctly for screenreaders.

No such screen reader exists, so you could claim it's a bug in all of them, but it's not a useful position to take. Screen readers are tricky enough to write without having to second-guess people who are trying to hide-but-not-hide text.
