+Subject: [PATCH] Add missing null pointer check in QQuickPopup
+
+Otherwise in certain circumstances this causes
+null pointer dereference induced crash.
+
+This is only relevant when the new Qt 6.8 feature
+`popupType: Popup.Window` is used where it makes
+it possible for Quick Popups to have their own
+independent windows.
