+Subject: [PATCH] waylandclipboard: roundtrip to get accurate focus state
+
+The current approach is too complicated and not correct anyway.
+To summarize QGuiApplication::focusWindow is delayed so the focus
+watcher was introduced, however when the window is hidden and
+setMimeData called before Wayland events have been processed,
+then focusWatcher is naturally out of sync, so the check
+was complicated to work around this state. However the same
+issue arises when the window is deleted before calling
+setMimeData.
+Instead of introducing more complicated checks and workaround
+roundtrip so the focusWatcher state is up to date before setting
+the clipboard.
