reCAPTCHA V2, IE11 and Punycode domain, NOT WORK

[YuuWoods]

I was set up reCAPTCHA V2 for my site. But, IE11 and Punycode domain, NOT WORK.

I try to check, check-box, but, I can't.

I try to use Chrome, WORK.

(https://www.郵便番号検索.site/r_test.php)

I think, IE11 use URL,  '郵便番号検索'. Not 'xn--wtqs6h80x7hlmmj423a'.

I think, this is cause to this issue.

Because, setting domains only 'xn--wtqs6h80x7hlmmj423a.site' by my reCAPTCHA control panel, reCAPTCHA shows 'ERROR for site owner:Invalid domain for site key'.(use IE11. If I use Chrome, work.)

Then add '郵便番号検索.site', show normaly,

I use test Site key: 6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI of https://developers.google.com/recaptcha/docs/faq, work.

Is there any solution to this issue?

Thanks for read all my message.
