Issue when iframe is present in the page

[ukoo-jordan]

Hi,

I encountered an issue, if an iframe is present in the page, it seems to prevent PrettyBlocks, to generate the preview, loading of blocks, boot context, zones. No error, no warning. When I desactivate this iframe, it seems to work fine.

My iframe code is:

<iframe id="{$iframe_id}" src="{$iframe_src}?prefill_user={$customer_email}" width="100%" height="1000" scrolling="no" frameborder="0" style="border:none;"></iframe>

$iframe_id and $customer_email are correctly defined.

Prettyblocks seems to blocked at this point. Prettyblocks is on v3.0.7, but I updated the prettyblocks iframe with the 3.1.1 sandbox attributes and it does the same.
