https://ast.wikipedia.org/w/index.php?title=Peligru_Mariellu&diff=747158&oldid=747157 shows 1922 being replaced by [[MediaWiki:Badtitletext]]. https://ast.wikipedia.org/w/index.php?title=Peligru_Mariellu&diff=747160&oldid=747159 shows "sieglu XX" being replaced by [[MediaWiki:Badtitletext]]. Nothing is known about the user's browser, skin, or OS.

This may be a duplicate of bug 70960 if the user did insert a "./" in the link content part. Otherwise, it may be another instance of bug 70894. But leaving this open for now in case we can figure out more about what the user typed there in the links.
