Thread:User talk:CodeCat/Why are links removed after transliterating usexes?

I added a tracking category to the Yiddish transliteration module and it works fine everywhere except usexes, where the link is stripped and the category name is displayed as plain text (see for an example). It seems that not only are links removed before passing text to the transliteration module, but also after. Why is this done and can you fix it? As a side note, it may be wise to make the link remover function smarter with regard to links that don't display text, such as categories and interwikis (although this would not solve the issue at hand).
