Description Mikhail Labanov 2021-09-28 18:13:57 PDT 
Steps to reproduce

1. Create a web extension for iOS 15
2. In context of WebExtension's background page set a cookie for a domain:
window.browser.cookies.set({
   name: 'mycookie',
   value: '123',
   url: "https://www.example.com",
   domain: ".example.com",
   expirationDate: Date.now()/1000 + 60*60
})

Expected outcome:
A cookie "mycookie" is set with expiration date of now + 1 hour for the example.com domain

Real outcome:
A cookie with expiration date exactly 30 years in the future + 1 hour is created
(year 2052 as at the time of this bug is filed)

The same is true for Desktop Safari WebExtension as well

The fix for this issue needs to be made outside of the WebKit project, therefore marking as "RESOLVED | MOVED".

We believe this issue is fixed in:
iOS 16.0 Beta 1 (and newer)
macOS Ventura Beta 1 (and newer)
