I have the following problem in SFSafariViewController.
It looks simliar to the CVE-2018-4110 bug.
https://nvd.nist.gov/vuln/detail/CVE-2018-4110
Does anybody face the same problem?
## Step to reproduction
**When visit new page**
1. Open a website by Safari
2. Go to the app which uses SFSafariViewController
3. Open the same website in SFSafariViewController
4. It occasionally reads cookies from Safari.
**When reopen the same page again**
1. Launch an app which uses the SFSafariViewController.
2. Open a page in SFSafariViewController.
3. Close and back to the same web site again.
4. It occasionally reads cookie from the previous session of the same page before new cookie is set.
## Expected behavior
SFSafariViewController should not read cookies both from Safari or from the previous session.
## Environment
iOS 11.3.1
iPhone X
