The onion pick only bypassed the SSO issuer, so a clearnet CDN, asset or dashboard host an onion page loads went through Tor, which the lab network cannot exit. browser_proxy_bypass derives the list from the deployed applications' domains plus the issuer; it is empty on a clearnet pick and on a tor-only node. Specs that passed their own proxy to newContext dropped the bypass and now inherit use.proxy.
