It's also set in

Not exclusively an "accessibility" related setting, but a display setting.

thing being cut off means they're cut off and you can't get to them.
think overflow:hidden in CSS.

The appearance of scrollbars, rather than reflow, is perfectly fine in
light of 1.4.4. See for instance the understanding doc
https://www.w3.org/WAI/WCAG21/Understanding/resize-text.html under

"A user uses a zoom function in his user agent to change the scale of
the content. All the content scales uniformly, and the user agent
provides scroll bars, if necessary."

This is exactly why there was a need for an additional 1.4.10 SC for reflow.
