Challenge window doesn't close after success in IE11

[rarenal]

Hello,

I'm using angular2-recaptcha for my Angular 4 application. It works as expected but there is a small bug in IE11:

When the reCAPTCHA challenge appears, a modal with images is opened

After completing succesfuly the challenge (clicking the Verify button), the modal should close automatically, and it does in Chrome, but not in IE 11 or Firefox (54.0 in my case). No error message is shown, but the Verify button remains disabled and the only way to close the modal is clicking outside it. The callback is done succesfuslly, which means is only a visual bug.

Do you have any idea on how to solve this?

Thank you and regards,

Did you see any console errors?

There is no error message in the console. Can you reproduce it?
