Hi,

I found a cookie bug which behavior is weird, and it happens on safari and chrome on iOS device

current behavior:
1. open safari, and set safari preferences of "safari opens with" to "all windows from last session"
2. create new page like below attachment
3. create a new tab than making a request to server on the page, server responses data which includes set-cookie header like below

`
Set-Cookie: XSRF-TOKEN=767e3675-d094-4af5-a9ab-330529151523; Domain=fleet.dev.aaa.com; Path=/; Secure; SameSite=Strict
`
and obviously I can read XSRF-TOKEN by calling `document.cookie`
4. close whole browser by using shortcut key `command + Q`, and open safari again
5. then call the request again, server also responses data which includes set-cookie header like below
`
Set-Cookie: XSRF-TOKEN=767e3675-d094-4af5-a9ab-330529151523; Domain=fleet.dev.aaa.com; Path=/; Secure; SameSite=Strict
`
6. and you will find that js can't read XSRF-TOKEN by calling `document.cookie`

I found that js can't read XSRF-TOKEN because the page restored from last session, but js can read XSRF-TOKEN because the page opened from a whole new tab

This sounds like something CFNetwork should look at. Or possibly Chris Dumez with the recent changes to document.cookie.

If calling same request again, which includes the XSRF-TOKEN cookie, but not show on web inspector

Hi,
I was stuck by this issue for a long time.
Does anyone have any feedback?

If you had a live test case that worked as expected in another browser but is broken in Safari, that'd go a long way in helping to explore it.
