Redlinking in warning edit summary for articles starting with "/"

I believe I found a minor bug. See bottom edit summary [https://en.wikipedia.org/w/index.php?title=User_talk:2602:306:8B22:7C40:4076:2F45:59A0:910C&action=history here]. I reverted an edit on [[:/æ/ tensing]]. When Huggle warned the user, it properly linked to the article in the actual edit, using <nowiki>[[:/æ/ tensing]]</nowiki> as shown [https://en.wikipedia.org/w/index.php?title=User_talk:2602:306:8B22:7C40:4076:2F45:59A0:910C&oldid=786529500 here]. In the edit summary, however, it did not use the ":", resulting in <nowiki>/æ/ tensing</nowiki>. This causes a redlink in the edit summary pointing toward "whateverpageyourecurrentlyon/articlename" like this: /æ/ tensing (for example, on this page it points to "Wikipedia:Huggle/Feedback/æ/ tensing").
