CONSOLE ERROR: line 8: Unsafe JavaScript attempt to initiate navigation for frame with URL 'http://127.0.0.1:8000/security/sandboxed-iframe-form-top.html' from frame with URL 'http://127.0.0.1:8000/security/resources/sandboxed-iframe-form-top.html'. The frame attempting navigation of the top-level window is sandboxed, but the flag of 'allow-top-navigation' or 'allow-top-navigation-by-user-activation' is not set.

This tests passes if the sandboxed frame cannot navigate the top frame.

PASS
