Yes, I agree. But I don't think it's a scaling bug, IMO it's a table
rendering bug. E.g.
  <TABLE id="mytable" style="background-color:black;">
   <TR><TD WIDTH=512 HEIGHT=512 VALIGN=TOP >
     <IMG SRC="test.png" HEIGHT="100%" WIDTH="100%"></IMG>
  </TABLE>
does make the table 512 by 512, but not the cell.
  ~$ dcop konqueror-2748 html-widget3 evalJS '
  > document.mytable.firstChild.firstChild.firstChild.clientHeight'
return 66.
  ~$ dcop konqueror-2799 html-widget1 evalJS '
  > document.mytable.firstChild.firstChild.firstChild.firstChild.clientHeight'
return 64
  ~$  dcop konqueror-2799 html-widget1 evalJS '
  > document.mytable.firstChild.firstChild.firstChild.firstChild.height=512'
scales the image right.

BTW, I think I found why sometimes scrolling pages with images can be
slow. The images are scaled.
