Hold.  No one claimed anything about behavior for plug-ins.  The claim 
made was very specific: an <object> loading HTML behaves just like an 
<iframe> loading HTML.  The discussion was specifically about loading 
HTML.  Plug-ins are irrelevant.

<embed> can't load HTML.  <iframe> and <object> can both be targeted 
with <a target="something"> at least in Gecko.

Any way it wants to, subject to same-origin restrictions.  No difference 
for <iframe> vs <object> if you reach in via contentDocument.

What Adam and Maciej and I are telling you is that in at least Gecko and 
Webkit they _are_ in fact the same thing, for purposes of HTML 
rendering.  As in, the same exact code is used to implement HTML 
rendering in all three.

I'm not sure what you're trying to say here....

Was someone suggesting doing that?  I must have missed it....  Can you 
point me to the relevant mail, please?
