I've experienced this as well, although I can't seem to reproduce it reliably. Just now I tried several times to cause it to happen again but it happened only once. In my case, the link itself is unclickable (and double-clicking in that area just opens the channel central window) but there is a clickable region exactly one line above (not below) the link, although that may just be because of the direction I was scrolling?
I just got it to happen again, this time the clickable area was TWO lines above the link.
