Yes. Mozilla is correct. Opera7 and IE6 have a bug.

No, in the case of Opera7 and IE6, the right margin becomes negative while
the left margin is zero, while in Mozilla's case the two margins are both
equal to the same negative value.

The spec is very clear that the two margins must be given the same value
in this case.
