A smarter way to handle it is to scan the undo list at the end of
edit-rectangle, and convert those specific undo entries so that they
describe the same changes as having been made directly in the buffer.
That way, you could undo those individual changes one by one.

Perhaps duplicate the last line of the surrounding text so that you have
enough lines to put the rectangle into.
