Contact Form Not Submitting using Ajax – Bug Found

All of our contact forms fail when using ReCaptcha v3 but work when disabled or using v2. Furthermore, at least one site processes using a form post (reload page) instead of Ajax.

It seems wordpress is stripping empty P tags. The issue is caused in a line in ../wp-content/plugins/contact-form-7/includes/contact-form.php; Umetzu found the issue: https://www.ads-software.com/support/topic/contact-form-doesnt-send/#post-14164972

Please push an update, this is causing a lot of issues.
