Title: Fix annotation clipping

Although annotations are still terribly ugly (please let some UI/UX guy look at it) and many types not supported, this fixes bug #1280.

It simply sets the `overflow` property of `.page` to `visible`. I'm not sure why it was on `hidden`, but until now, I haven't seen the change brake anything.
