+Subject: Backports crrev.com/c/1152083
+
+This backport ensures that the cookie store is always created. We use a
+code path that didn't previously create the cookie store internally,
+which caused all cookies to be deleted when the application was closed.
+
+This backport can be deleted when the C70 upgrade lands.
