Text-clipping / overlapping is already called out in the understanding doc as a failure of text-spacing, can we consider contrast a part of that?  The same goes for resize/reflow.

The question I have then (as a tester) is whether that should be failed under contrast or the triggering condition? My gut says it should come under the SC that triggered it, as solving that problem will be a layout or text-buffer change.

WCAG 2.0 did a good job of things failing in one place, we should try to maintain that.

For most sites you can test that by:

  *   zooming in gradually to 320px looking out for omissions or clipping
  *   apply text-spacing
  *   zooming back out to the default looking out for omissions or clipping.

If it fails whilst zooming in, it’s a 1.4.4 / 1.410 issue (depending on what level), if it only fails on the zooming out it’s a 1.4.11 issue.
