fallback does not fire callback about recaptcha

[rowan-m]

I'll pass this on to the team, but my suspicion here is that that because the fallback UI is super stripped down it may not fire the callback by design. I was just testing this here and I get the same issue as you: add the fallback, lose the callback.

However, you can still use the g-captcha-response in the POST data to do the verification when the form is submitted here (i.e. the flow shown in the example). I'll ping you back @defualt when I've got some confirmation.

Oh! In order to succeed with the fallback, you have to complete several screens of picture grids, arrive at the copy-and-paste section, and then submit your form. I thought that "verify" button for each picture grid really meant "verify". To the naive user, when the proceed through the 3 required picture grid tests, they will think they are actually failing each test, when if fact they are succeeding at a step, maybe. And I see now that the textarea you paste into after 3 picture grids is where the form derives g-captcha-response for the POST. I thought the copy and paste thing was a last ditch I'm-not-a-robot test.

This is really unusable. Especially on Android 2.3, I am unable to paste that text. When I long press I only get a dialog for input method.

Is there a way to force non-fallback on old Android?

Thanks for your attention @rowan-m

edit: I just tried forcing non-fallback in Android 2.3 by setting window['___grecaptcha_cfg']['fallback'] = false before calling render on recaptcha. It actually created the non-fallback animated checkbox. But upon tapping, the checkbox animation keeps spinning and doesn't proceed. Oh well.

@rowan-m I made a screen recording showing how Android 2.3 is unable to pass the recaptcha due to the copy-paste requirement. https://www.youtube.com/watch?v=EP5eO9Ld5Gk&feature=youtu.be

While the user experience is not amazing here, it is currently working as intended since the minimum browser requirement here is Android native browser 4.0+.

To copy and paste the code successfully, I needed to:

1. Long press on the first text field, tap "Select all"
2. Long press on the selected text, tap "Copy".
3. Long press in second text field, tap "Paste".
