Issue description:

I have a Widget prefab with UICanvas as its root. the first child of it is a CanvasScaler.
With these properties:

Then I added a container control, called Building Buttons,with bounds and pivot as Horizontal Stretch Bottom. As seen below,

I assumed that the Widget prefab editor and the Game scene (after adding it into the Scene window) it will be a 1:1 ratio. However, it is not the case.

As you can see below, the Building Buttons is smaller than what was shown in the Widget editor. Even though it has the same Transform properties.

Game View port size is 1920x1080

Work-around
One solution is to just re-edit the Widget prefab in the Game Scene and just apply the changes to the prefab.

• That is what I did with the button on the top left
