Not an expert in Trusted Tester itself, but purely from a WCAG 2.1 point
of view, this would fail 2.1.1 if there's no way for a keyboard user to
scroll. I'd say the scrolling/need to scroll is a "user-activated
functionality". Arguably, browsers should handle this gracefully
themselves (see for instance Firefox, which automatically makes an
<iframe> - I assume you're talking about iframes here? - focusable by
default, so keyboard users can always get to the iframe itself and then
use their cursor keys etc to scroll). But as that's not the case in all
browsers, authors need to consider this themselves.
