A user wrongly removed many sitelinks from an item page. I went to the item page's history and clicked on a good previous version. When I tried to reset the item page to that version, I got a page that showed Wikibase-validator-sitelink-conflict as an error message. All the links appeared as HTML - for example "<a class="external text" href="//en.wikipedia.org/wiki/Missa_solemnis_(Beethoven)">enwiki:Missa solemnis (Beethoven)</a>" instead of "enwiki:Missa solemnis (Beethoven)" as a clickable hyperlink.
The title of the page was the message Wikibase-undo-title, and it showed "$1" instead of the item's label.
My UI language is Hebrew.
The item I was trying to restore is https://www.wikidata.org/wiki/Q723790 .
The version I was trying to restore is https://www.wikidata.org/w/index.php?title=Q723790&oldid=123262931 .
