>> When a top-level HWND is iconified its window rect is updated to a hard-coded location (something like -32000, -32000) and a smaller width and height. For this reason we should not send notifyMove or notifyResize events for an iconified stage.  This PR adds a check while handling WM_SHOWWINDOW to catch the case where a stage is hidden while iconified. This matches similar existing checks like the one for WM_MOVE.
