Understanding 1.4.11 - recent additional image incorrect

[patrickhlauke]

Recently #2028 this new example has been added to the 1.4.11 understanding https://w3c.github.io/wcag/understanding/non-text-contrast.html

Note that this Success Criterion does not directly compare the focused and unfocused states of a control - if the focus state relies on a change of color (e.g., changing only the background color of a button), this Success Criterion does not define any requirement for the difference in contrast between the two states.

Figure 15 The change of background within the component is not in scope of non-text contrast. However, this would not pass Use of color.

However, the image doesn't match up with the prose - as it's not just the background that changes here, but the colour of the text as well (and a dramatic change here from white to black, the most contrasty change possible).

Suggest changing the image so that the three buttons are the same except for a change of just the background

@patrickhlauke I think this issue should be closed but I don't know which PR closed it.

For me, this is fixed in the 2.2 version: https://www.w3.org/WAI/WCAG22/Understanding/non-text-contrast but not in the 2.1 version https://www.w3.org/WAI/WCAG21/Understanding/non-text-contrast

You're right! I didn't check the 2.1

WCAG 2.1 informative docs have now been republished with this fix, made possible by #4007.
