DOMException: Blocked a frame with origin

I got a problem with printing with the first few buttons on https://printjs.crabbly.com/ :

Console error:
````
Uncaught DOMException: Blocked a frame with origin "https://printjs.crabbly.com" from accessing a cross-origin frame.
at u (https://printjs.crabbly.com/print.js?v1.5.0:1:4095)
at HTMLIFrameElement.n.onload (https://printjs.crabbly.com/print.js?v1.5.0:1:5017)
````

I think it has to do with the variant because the `https://printjs.crabbly.com` is not equal to `blob:https://printjs.crabbly.com`

Reproduce the failure using the first few print buttons on https://printjs.crabbly.com/ and inspect the print.js?v1.5.0 iframe onload path shown in the console stack. Pay particular attention to the blob iframe and its cross-origin access; the issue is done when those buttons print without the DOMException.
