Subject: [PATCH 1/2] Change JsFooterInlineCode to allow any
 #g--recaptcha-{uid} ({uid} > 1000)

Do not iterate from 1 to 1000 and check if there is a matching #g-recaptcha-{uid} div on current site, but iterate over existing .g-recaptcha elements and call grecaptcha.render(...) based on that .g-recaptcha elements.
