2.4.3 focus order with non interactive element with tabindex="0"

[Ignacio-de-Loyola]

This is the example about ARIA tabpannel that element has tabindex="0".
ARIA Authoring Practices Guide

The example where non-interactive elements(tabpannel) would have a tabindex="0" attribute you invalidate 2.4.3?
(In this case, non-interactive elements(tabpannel) would have not a scroll)

In general, the answer is no, it won't fail 2.4.3 - have a PR waiting here that should hopefully clarify things a bit more #1643

Would the ability to scroll make it interactive?
