+Subject: [PATCH] QQuickItemView: Fix max(X/Y)Extent()
+
+QQuickFlickable maxXExtent() and maxYExtent() return the amount of space
+that is not shown when inside a ScrollView. QQuickItemView however just
+returned width() if vertical and height() if horizontal. In these cases
+just defer to the QQuickFlickable base implementation like minXExtent()
+and minYExtent() already do.
+
+Fixes: QTBUG-83890
+Pick-to: 5.15
