Macy and iframe (google reCAPTCHA v2)

[RolandTi]

Hello,
I added a google reCaptcha in a Macy instance.
It seems to me that the iframe from google is so long to load that Macy doesn't calculate it. (screenshot 1 with macy over the footer's line).

But if I resize the window, Macy recalculate everything and it's ok (screenshot 2).

So I tried this solution to force recalculate on the first page's load
but nothing happened. Any clue ?

<script> window.onload = masonry.recalculate(); </script>

Thanks !
