Adding Widget Resize to BoxLayout function
Adding Widget Resize to BoxLayout function

- Widget might be using not just View but other mechanisms for rendering
  aware of the view size (e.g. ViewPort).
- By updating the view reference out of Widget, Widget doesn't have a
  chance to react on this layout algorithm
- That's an existing bug that happens when we try to use CellView inside
  of an BoxLayout
