Widget doesn't auto move up when removing widget like the follow image situation
Remove the test1 widget, the test2 widget will not auto move up.
Root cause: when initialize, the right part of the test1 widget is undefined. So when removing the test1 widget, it will judge the undefined part whether empty, but the is_empty function will return false, so the test2 widget will can't be moved up.
