Organization Invitation Applies on wrong account

As an organization owner, I want to invite A to join my org and I send an invitation to him.

A is now using b@test.com in his browser and when he opens the invitation email and clicks Join @Org the account b@test.com will be joined and the expected email account A cannot join the org except sending the org invitation again.

So I think when the user clicks the invitation link, Github should check if he is the right person the org want to invite
