That's a fair report. CQ figures out CL dependency from codereview, and codereview considers dependency satisfied if previous CL has been closed (I think, not 100% sure). Because v8 and chromium use contraption to add footers to commit messages, it's hard to fix this in CQ + Rietveld.

But fear not, issue 626103 would decrease the likelyhood of this problem significantly.

Note, that strictly speaking there is still a race condition because not all git mirrors are consistent, hence it'd still be possible that some bots won't see latest HEAD even without the contraption which issue 626103 is aiming to remove

No idea if this is an issue any longer in gerrit...

Yep, it's not a problem in Gerrit.
