FEATURE REQUEST: grecaptcha.render should honor the STRING set by container var when rendered (PS: popup bug, recapcha displays off screen)

[zagarskas]

FEATURE REQUEST:
When grecaptcha.render() is set and a container is passed in as a (string) please honor the string by passing it into the DIV container element that the grecaptchaPopup element appears in by adding id="container_string" or id="[container_string]+[opt_widget_id]"

Also note, opt_widget_id is simply a numeric id, and does not honor container(string) either.

Here is a problem which occurs when grecaptcha.render() is called during a modal-popup where the HTML element scroll-y position is frozen, creating a problem where the user can not interact with the grecaptcha challange (because it is hidden off screen)

If we had some way to easily determine the container ID of the rendered grecaptchaPopup then we could correct this offset however we see fit.

PS: if you have any ideas how to accomplish the following goal, please let me know, I am open to any ideas here
When a grecaptcha challange is triggered inside of a modal popup AND the body/html scroll-y position is FIXED because we want to prevent scrolling ensure that the grecaptcha challange is always visible.

Popup Issue:

• Install a modal popup that locks the body/html element scrollbar
• place a form into the modal popup
• place several anchor tags on the page that trigger the popup
• scroll down on the page, fire the popup (and grecaptcha.render() )
• the grecaptcha challange will be OFF PAGE at some point when the scroll bars are locked
• The challange can not be seen, therefore can not be met
