The Slang Standard Library Reference has a section that is inaccessible because it doesn't have a title that can be clicked. You can open the sub-sections but not that section itself. There doesn't appear to be a way to get to it.

Direct link to a child of the missing node here.

(Aside:, the "Miscellaneous types" section title visible a little further up is misspelled "Miscelaneous types".)
