| CONSOLE MESSAGE: line 20: Blocked form submission to 'http://127.0.0.1:8000/contentdispositionattachmentsandbox/resources/form-submission-frame.php' because the form's frame is sandboxed and the 'allow-forms' permission is not set. | |
| This test verifies that form submission is disabled when 'Content-Disposition: attachment' sandboxing is enabled. A security error will be logged to the console if the test passes. | |
