Path to reproduce:
1) switch to list view in the CM;
2) click `preview` link for an SSR SPA.
SPA gives 500.
SPA works normally.
SPA detects the preview mode and tries to fetch a page model via preview URL but it fails because there is no JSESSIONID cookie under `/site`.
Perform SSO handshake before opening the link.
