Calculations for criterion 2.4.13

[natPL903]

In understanding is calculating the focus area (https://www.w3.org/WAI/WCAG22/Understanding/focus-appearance.html).

Outline 2px adds 4px to the width of 90px (2px left and 2px right). Same height. Meanwhile, we have 92x32. In my opinion, this is a mistake.

I believe this is the result of the SC wording being altered (in regard to the 2px area language) when it became a AAA criterion, without the examples being updated to reflect the new language.
