WebCTR also leaks information after $2^{n/2}$ blocks, but in a different way; here a collision is impossible, and so the information leak is that there are no two CTR output blocks that are exactly the same (and when you go beyond the birthday bound, you would expect one); this is also an information leak (albeit a far more subtle one).
