The markdown preview ran cooked-element decorators before oneboxes
loaded and ne…ver again, so anything decorating a onebox, such as the
event card for event topics, only appeared after the next keystroke. The
preview now re-cooks once a onebox or inline onebox loads, so decorators
and inline titles show up immediately.
Re-cooking rebuilds links that are still loading, which would queue them
again, so the onebox queue now skips fetching a URL an earlier entry has
already resolved.
