This is a regression from Bug 300030.

I think this is the same as bug 441400.  The case referred to there doesn't have the container floating like this case but looks the same otherwise.

Similar result with 
  position:absolute; right:0;
instead of
  float: right;

Probably related with bug 349255.

Do other browsers (e.g., Safari, Opera) match the Firefox 2 layout, the Firefox 3 layout, or do they put one below the other?

Fx2, Opera9.6, IE7, IE8 beta2 match.
Safari 3.2 does the same as Fx3

[Zibi Braniecki [:zbraniecki][:gandalf]]

Webkit nightly does the same as Fx3
Opera 10 does the same as Fx2
