A file's PDF part draws a right-to-left paragraph's words in the order
they show ("mm 120.5"), while its text object keeps them in the order
they are typed (" 120.5 mm "). The page's type was matched to the text
objects by their letters in order, so it matched none and stayed beside
the label as a second copy. It is now matched word by word.
A point type label turned a quarter (a vertical dimension's) lay outside
the box its text object was looked for in, which was always level; that
box now runs along the type's baseline.
