[css3] fit and fit-position

Has anyone implemented 'fit' and 'fit-position'
<http://http://www.w3.org/TR/2002/WD-css3-box-20021024/#the-fit> ?  I
have some questions...
 
Is the replaced object still considered to be 'in flow'?  Or is it
'positioned'?  (This seems to be a form of relative positioning.)
In cases where the replaced object fills its containing box, is it
positioned on top of preceding non-replaced inline content (i.e., closer
to the viewer)?
In such cases, is the object positioned underneath any subsequent
non-replaced inline content (i.e., further away from the viewer)?
 
Best wishes,
 
Melinda
