Re: WCAG On input with Auto radio button content update

This fails WCAG 3.2.2.
Automatically moving focus when you change the setting of a control
(i.e. select a radio button), falls under the 3.2.2 definition of
"change of context".

Also one could argue this fails content order, (if the content that
gets updated comes, in content order, before the controls used to
update it).

If you placed the radio buttons before the content and did not move
focus to the content when you select them, this would be passable,
better yet if there is a "go to updated content" button after the
radio buttons.
Yes, aria-controls should've solved this situation (not the movement
of focus but being able to navigate from a control to the content
affected by that control) but, in the words of a famous accessibility
rock star "aria-controls is poop":
