Special:UnconnectedPages has a option "Only pages with interlanguagelinks", which is lost, when clicking on one of the limit option or using the next/previous link ("View (previous 50 | next 50) (20 | 50 | 100 | 250 | 500)")
More things: limit is lost, when input a new page name or check iwdata and submit. The submit value is part of the get url, this looks unusually.
Just checked on enwiki and this appears to have been fixed at some point! http://en.wikipedia.org/w/index.php?title=Special:UnconnectedPages/sdf&limit=20&offset=60&iwdata=only If I am wrong please just reopen the bug!
