TLS errors will emit WebKit.WebView.SignalSignatures.load_failed_with_tls_errors | WebKit.WebView::load-failed-with-tls-errors and, if the signal is handled, finish the load. In case the signal is not handled, WebKit.WebView.SignalSignatures.load_failed | WebKit.WebView::load-failed is emitted before the load finishes.
Ignore TLS errors.
Enum values used to denote the TLS errors policy.
