Steps to reproduce the issue

Login with passkey and have xdebug enabled.

Plugin events 'onUserAfterLogin' and 'onUserLoginFailure' in plugins/system/webauthn/src/PluginTraits/AjaxHandlerLogin.php are missing the required 'subject' and or 'options' value for the event.

Expected result

Login without an error.

Actual result

Just an example when one of them failing.
