That rectangle indicates the boundaries of the layer. When you pasted
to a new layer, the resulting layer is only large enough to fit the
content that was pasted.
If you want to extend the boundaries of the layer, execute
"Layer->Layer to Image Size" (or, alternately, manually change the
boundaries using "Layer->Layer Boundary Size...").
