Now I can interact with the toggle details string, but nothing happens when I do. Since you've made it a link, I'm going to interact with it that way. Are you expecting it to be clicked on rather than selected as a link?
Other accessibility problems: * The page is hard to navigate. There are no headings, and none of the screen reader controls for navigating the page work, so you have to scroll through the whole thing. * In the table listing versions and letting you look at the changelogs/control files/etc, we have the same hard/impossible to interact with items problem as with the action needed display. --Sam
