It does for me: the attached image shows four buffers containing the
checkbox.svg and checkbox.xpm images from /etc/images.  The leftmost
buffer shows the default font size, the other buffers show increases of
the font size successively by two steps with `C-x C-+'.

(The rightmost buffer shows another oddity: the line number is
supposedly 47.  This number appears when the cursor moves from 'T' to
'e'.  This also happens in the other buffers, but only those with
increased font size show line number 47; in the leftmost buffer, it
shows line number 27.)
