The Google reCaptcha works when posting a comment.
It also works when posting a reply to a comment.
When posting a reply to a reply to a comment, however, it fails with an "Invalid Captcha" error message.
There is a recaptcha error listed in the Developer Tools console:
recaptcha__en.js:412 Uncaught Error:
ReCAPTCHA placeholder element must be empty at Object.Nq [as render] (recaptcha__en.js:412) at onloadCallback (wpdiscuz-recaptcha.js:4) at Aq (recaptcha__en.js:407) at recaptcha__en.js:416 at recaptcha__en.js:427
This is happening on all of our sites, but it was first observed here.
