I tried that, and the "marching ants indicating the center (original)

image stayed, and more such ants were added to the entire widened
image. Commands that were grayed out were still unavailable.

Open the layers dialog (Windows/Layers, Channels, Paths, Undo)

Then right click on the layer with the original image, and select "layer to image size"

After that you should be able to flatten the image.

Or you could just select File/Save As
then supply a new image name and you will be prompted to export the image, which will flatten it since jpg images have to contain only one layer.
