+Subject: [PATCH] containments/panel: Fix initial sizing
+
+Timers for anything that affect layouts are universally wrong.
+
+Ultimately this breaks layouts internal usage of QQmlParserStatus. For
+runtime changes layout internally most relayouting is buffered
+internally till the polish event which is once per frame.
+
+Removing this makes startup faster, less glitchy and more declarative.
+
+
+(cherry picked from commit b2fd1578a0063938a3eda8d8e41f14394b7635f7)
