When both, the VisualEditor and ConfirmEdit extension, are installed and the ReCaptchaNoCaptcha module is used, then editors who require a Captcha check can not save their edit. The API module for ReCaptchaNoCaptcha is currently not handled by the VisualEditor integration in ConfirmEdit. Therefore, an edit that is aborted by the captcha module is recognized as a general, not handled error in VisualEditor.
It would be great if ReCaptcha would be supported in VisualEditor as well, so that the edit of users who need to solve a captcha is still being able to be saved.
