In addition to breaking pagination as mentioned in other comments, this site breaks "open in new tab" functionality, whether by ctrl-click/cmd-click or by "right click, open in new tab".

When reading Wikipedia to learn quickly about something, I frequently "open in new tab" a raft of pages so that I can continue with the main subject then quickly go to the additional information of interest.

On this site, cmd-click simply acts as click (open target in current tab), while "right click open in new tab" just opens a blank page - as I found out to my irritation upon closing the original tab....

Poor, poor design, poor, poor UX.
