Comment view isn't "clickable"

Body

I'm a keyboard-only user. The new comment view does not seem to have been tested from an accessibility standpoint, I can't see the comment alongside the diff, and I can't expand any view of replies. I see that there are some UI items, and my tooling can sort of "see" them, but it doesn't seem like I can "click" them. I review very long pull requests for work and as a maintainer, please advise if there is any intention to allow disabled maintainers to use pull requests? Or any option to use an older version of the interface?

I suggest this is part of the regression introduced earlier (see https://github.com/orgs/community/discussions/172911 ) where an entirely impractical workaround was suggested, but it is still not possible with my assistive tech tools to add a comment to a pull request. In general I would expect that UI changes meet some basic accessibility standards such as having elements that can be focused and clicked.
