The markup is missing some text context that is already added to aspnet/Templates (to be a good, web citizen). They originally missed this as well:

The Semantic UI should have something similar for screen readers, if not, it'd be nice to provide an util class for this, add to site.css and just use it in markup.
Otherwise current toggles are just clickable, because some people just see they are on the screen. This is not bad markup, but templates should do better.
