In an object page with a few Aliases, e.g. https://www.wikifunctions.org/view/en/Z10944
each of the Aliases is contained within a separate <ul> tag.
This causes a WP:LISTGAP problem (whereby screenreaders will treat a list of 4 items, as if it's 4 separate lists of 1 item). -- I have user.css that adds a dotted line to detect this problem in wikipages, hence I noticed it!
(Possibly this is a duplicate of, or related to, T336347: ChipContainer and Chip components: Decouple these componets from the internal structure of zobject data, but I'm not sure.)
