`extract_original` split the wrapper's inner text on newlines and kept the
first and last pieces, which are the line breaks around the original
element inside `<div data-impeccable-variant="original">`. Every discard
therefore left one empty line before and one after the restored element.
`extract_variant` already trims those; the original now gets the same
trim. Test writes a JSX wrapper to disk, discards, and checks the file
byte for byte.
