It will remove delegates, and it will re-render the list. +// When e.g. QQmlListModel::remove is called, the removal of the delegates should be done on +// QAbstractItemModel::rowsAboutToBeRemoved, and the re-rendering on +// QAbstractItemModel::rowsRemoved. Currently both are done on the latter signal. The problem is +// that the destruction of an item will emit a changed signal that ends up at the delegate, which +// in turn will try to load the data from the model (which should have already freed it), resulting +// in a use-after-free.
