I think the goal is to try and guess within the current viewport, where the author has their attention...so perhaps when zooming-in:

- the system maintains the same top-left (top-right for RTL) corner UNLESS there is a focussed/selected content INSIDE the pre-zoomed viewport, in which case that remains in the post-zoom viewport.
- note that I say "content" and "selected", because there may be cases where the viewport is zooming in to just part of an element (e.g. if I select a few words of text that are part of a <p> and zoom in)


Cheers,
Jan
