I don't think we can do much other than apply a layer-wide filter,
to edit image content that is off the canvas.
In situations where I need to work with things that are off the
canvas, I make the canvas large enough to hold everything that
extends past the intended "final" dimensions of the image, then crop
the image or restore the original canvas dimensions later.
To keep track of the original canvas boundaries, add guides by doing

The guides mark the boundaries of the original and/or final canvas,
and make it easy to crop the image to those dimensions. Or, select
the area marked by the guides and do Image > Fit Canvas To Selection
to restore the original canvas dimensions and preserve the
