You have put your entire UI into a container without a layout, and have not added any layout code.
This is not a good idea, you should consider using a standard layout or actually putting layout code in your app.

	space := container.NewWithoutLayout(spaceNormal)

However, I think the bug you are describing is a duplicate of #4431
