Research update for HackTricks content

🤖 Agent Actions

Summary:

1. Updated the credentialless iframe notes to reflect storage partitioning by a per–top-level document nonce, enforced noopener on popups, and autofill/password manager restrictions, aligning the section with the current WICG explainer details. (wicg.github.io)
2. Added fetchLater operational cautions (limited/experimental availability, no response access, connect-src CSP control, and unload/activateAfter timing) in line with MDN and the Chrome origin-trial writeup. (developer.mozilla.org)
3. Added new references for the PortSwigger dangling-iframes research and MDN’s fetchLater() page in the References section. (portswigger.net)

Reference URLs used (blog posts):

If you want, I can also cross-check the rest of the XSS/CSP chapters for consistency with these updates.
