[Bug]: Double Like when liking from email notification and on P2 post

[andreabadgley]

Context and steps to reproduce

I received a notification to my gmail account today for a P2 post (p8wKgj-7ER). I unconsciously clicked "Like" from the email notification, then opened the post, saw that I hadn't clicked the Like button (the star was not filled in), and clicked the Like button. When I looked at the Likes on the post, I saw myself there twice: one with the WordPress.com gravatar I expected to see (blue background; user andreabadgley), and one with an old Gravatar I no longer use on WordPress.com but I do use for my gmail account (straw hat; user andreabadgleyec7e1d2b91):

The Like with the straw hat, which I presume was created via my Like click from email, should not be there. I'm not sure if this is internal to Automattic or happens for other users as well.

I'm moving this to In triage while I go over some details with @andreabadgley via Slack.

@Automattic/loop I'm looping you in on this one as I'm not sure what's actually happening.

Andrea received the notification at andreabadgleyec7e1d2b91 so not really sure what's happening here. Could these accounts be somewhat intertwined somewhere in the backend?

Yeah, we can take a look. Added to our board.
