I (first author) received a decision on a manuscript recently (minor revision). All my co-authors were cc'ed in the decision email and some of them replied to the decision email saying "congratulations" to me while cc'ing the other co-authors.

One of them accidentally cc'ed the EiC of the journal!!! Actually, his reply was to the EiC of the journal with me in the cc. I think this horrible as formally the paper is still pending minor revision before publication.

How should I react? Should I just ignore this or send an email to the EiC apologizing for the misdirected email of this co-author? I do not want to overreact but this got me anxious as I have been eager for this paper to get accepted.
