replies, conversation shows whole tree [COMPONENTS][Feed] Added request to FormatNoteList event Every single Note that was provided to FeedController::postProcess is shown. This means, that even though the Feed is formatted to show only a Note and its respective direct replies, those same replies are shown individually again (and they get the chance to show their own direct replies). The Note list provided to FormatNoteList is reversed, and for every index, the respective Note replies are filtered out of the original list. The replies are then added as leafs of the current Note and added to the tree.
