Update for 4chanx 1.2.2

Remove hover visibility toggle on X (for removing a thread from the watcher) this seems to help the flickering WATCHER header:

#watcher div > a[href="javascript:;"],
#watcher .close {
  visibility:collapse!important;
}

#watcher:hover div > a[href="javascript:;"],
#watcher:hover .close {
  visibility:visible!important;
}
.closed {
  padding-top:20px!important;
  padding-bottom:20px!important;
}
