Get deleted cookies in duplicate tab

[starofsky]

When I deleted one cookie, duplicate this tab, I can retrieve this cookie in Server.
I don't know what wrong here. Thanks

I created one example at link https://286q7d-3000.preview.csb.app/
Follow steps:
1/ Create cookie
2/ Go to index2
3/ Delete cookie
4/ Back to index
5/ Duplicate tab
6/ See console will see cookie deleted show on SSR

I update more repo https://codesandbox.io/s/misty-cdn-vdknrz
Note: you must do it twice for reproduce
