It seems to have a different effect: the last version at least has one 
size where s-f-a changes the height by 2 line heights.

See this transcript where at the end (and multiple times before that) 
change the frame to 118x35 (per GNOME) which is 112x35 internally, and 
s-f-a changes the height to 33 (per GNOME) which is 34 internally.

The lines xg_frame_set_char_size_return do appear in the transcript.
