From e0271324f05fee2c8670a73d1e7e89aef51532a3 Mon Sep 17 00:00:00 2001
From: Aleix Pol <aleixpol@kde.org>

Subject: [PATCH] QQmlDelegateModel: Refresh the view when a column is added at
0
It can happen that a model reports n>0 rows but columns=0 (See
QConcatenateTablesProxyModel). In those cases we would render glitchy
items until the elements are marked as dirty.
