Re: G142 and spatial relations

Thank you Patrick.

From a user perspective, if a user sees some content and zooms to see it clearly but that content disappears somewhere ( under a menu or at the bottom of the page) isn't that disorientating?

I thought upto 200% the page should scale uniformly and only after 200% the reflow/rearrangement has to happen.

If that were to fall apart after zooming (with an actual table column wrapping below/moving to the end of the page), then it would no longer be clear which what the relationship of that content is/which rows those cells belong to.
