Two weird things with content blocking:
(1) When there are already blocked images on the page, and you re-enter
content blocking mode, it takes a while to enter this mode, and meanwhile
the statusbar keeps flashing (I guess it's re-downloading or 'processing'
every blocked image)... This feels so slow, and doesn't seem to fit with
Opera's regular speed...
For example, go to http://www.slashdot.org and block one of these funny
icons (which will block all of them). Then press "Done", and re-enter
content blocking mode.
(2) When you block content and press "Done", the blocked content
disappears immediately. When you unblock content and press "Done", the
unblocked content does NOT reappear. Why's that?
