Expected: The wikitext [[mw:Category:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA]] (that's 255 As) should be turned into a sitelink.
Actual: The wikitext is shown literally.

Why this is a problem:
The category კატეგორია:საერთაშორისო ოლიმპიური კომიტეტის მიერ აღიარებული საერთაშორისო სპორტული ფედერაციები on kawiki has a perfectly valid title under 255 bytes in UTF-8. Yet, you cannot link to it from other wikis because the namespace prefix კატეგორია (and the colon character) add 28 bytes to the already pretty long title (232 bytes). I know you could replace "კატეგორია:" with "Category": to make it shorter but that's not the point here.
