polyfill does not work in google earth internal browser

[bboyle]

Google Earth has an internal browser that has unknown capabilities.

It has been reported that required radio buttons prevent form submission. Unsure why.

Required field tests report some issues. (To check the tests in google earth, add them as a link and then click the link to open the internal browser.)

Suggestion:

• on submit: Sanity check radio buttons failing required validation. Remove @required to allow submission
• check if google earth fires the submit event when it considers a radio button invalid (if submit event is not fired, this suggestion won't work)

[bboyle]

Failing when radio button is missing @required (but required is specified on another radio button in the group).

Script was not failing. The presence of other errors in the form leaves the radio button marked as required, thus causing the google earth bug. This was being picked up and displayed in the UI. Needs a different solution.
