Broken recaptcha on the Feedback form in the DeveloperZone

Tried to leave comment but it keeps telling me my vision is bad and to enter the correct letters shown in the captcha.

Ben, I just received and replied to your feedback.

Seems it worked finally?

After investigation, it seems our captcha (Dev Zone Feedback button) has an erratic behavior. Added to our TODO list.
