Thank you so much for reporting this! We've known about it but seeing all the 's from others who have been bitten by it is a valuable nudge for us to bump up the priority for fixing it!
In the meantime just reply to the legit check email when this happens and we'll take care of it.
(Btw, we like to send stickers to people who report bugs. Tell us your snail-mail address if you'd like some!)
