The problem is the layer is not resized with the canvas. You can use Layer -> Layer to Image Size
but for reference using your workflow, next time you use Image -> Canvas Size
Do not use Layers (resize layers) None
Which gives this
Use Layers (resize layers) All Layers
Which gives this if the image has transparency, otherwise you get the background color.
