2) Copy, yes, select no (in other words, they have to be selected by default). Try this:

By moving it around in the canvas window, you can check that it is totally filled, so the fill happened outside the canvas boundaries (which is already one case where Select-All and Select-None aren't equivalent)
- With the path tool, create a closed path outside the canvas but within the layer boundaries
- Select>From path. No marching ants. Notice that Select>None is grayed out, so there is no selection
- Edit>Copy
- Edit>Paste as>New image. The new image is 400x200, so the whole layer was copied.
