KoReader OPDS file support

Hi,

Just new to KoReader and I could setup my Calibre OPDS server. I managed to reach my server but I can't download any CBZ/CBR files. Simply no button to download my ebook. I read an issue talking about that and it's a known issuem but is it already fixed?

When browsing to my KoReader files, I found frontend/ui/widget/opdsbrowser.lua and saw the code

["application/x-cbz"] = "CBZ",
["application/vnd.comicbook+zip"] = "CBZ",
["application/zip"] = "CBZ",
["application/x-cbr"] = "CBR",
["application/vnd.comicbook-rar"] = "CBR",
["application/x-rar-compressed"] = "CBR",
["application/vnd.rar"] = "CBR",

already added, so why I still can't download CBR/CBZ files?
