.ai import: area type shows its first line in a substituted font (follow-up to #1264)

Area type whose frame is too short for a line of the font it shows in here
drew nothing: a font that isn't available shows in the fallback font, whose
line may be taller than a frame made for one line of the file's font (overset
type isn't drawn). Where the file itself lays lines out in the frame, the
frame of the imported text object is made taller, from its top, by what its
first line needs, and the open result says how many frames were.
