Popups are not QQuickItems so when updating the palette, we explicitly called QQuickPopupPrivate::updateContentPalettes for all children of type QQuickPopup of the application window. However, this didn't always work for tooltips when they were created via attached objects (QQuickToolTipAttached), which is a common way to create them. When QQuickToolTipAttached created the tooltip instance, the parent of it wouldn't be the parent item, but the QML engine. In this case we wouldn't find the toolTip in the list of children of the application window. To fix, we explicitly search for children of type QQuickToolTipAttached instead, whose parent is the parent item.
