WP_Error causes HTTP status code 500 when comment form ReCaptcha is not valid

[l3ku]

When having the setting "Forms to protect" => "Comment Form" applied and sending a blog post comment without ReCaptcha checked, returning a WP_Error from the function recaptcha_check_or_die added as a hook to pre_comment_on_post on https://github.com/mcguffin/wp-recaptcha-integration/blob/9d669d6b62b0306d08ef98e8a69f4af538ebcfe2/inc/class-wp_recaptcha.php#L152 causes the POST request towp-comments-post.php to return a HTTP 500 status code. As HTTP 500 status codes typically means "Internal Server Error", this is logged to my current testing/monitoring mechanism as an error in my website code. I think that a HTTP status 4xx would better represent the actual case happening here, as the ReCaptcha plugin functionality is functioning just as intended: that is, not letting the user submit the comment without ReCaptcha.

Is there any way to disable the HTTP Status 500 via WP Admin options or adding plugin provided filters/hooks to my website theme?
