Able to upvote migrated questions twice [duplicate]

Question

This question already has an answer here:

• Migrated question's answers can be upvoted twice by the same user 6 answers

Got a weird (or neat) bug here. This question was migrated from music.SE to sound design beta. I happen to remember that I upvoted if not all, all but one of the other answers on the question. However, since it has been migrated to sound.SE, although the answers preserved their votes from music.SE, I am able to upvote them again.

I remember, for instance, that I was the only one to have upvote the accepted answer. My upvote is still there, but I can upvote it again, giving me a double-vote power.

Not a critical bug, but still a bug that could use working out.

This is a known issue, but for such an edge case, we are OK living with it.
