dialog iframe Sandbox access violation

[gha]

When opening a dialog with framework the iframe seems to be sandboxed and get a Sandbox access violation.
This can be reproduced in Chrome or Safari.
How can I get rid of this?

Code: Select all

Refused to display 'http://localhost:8080/...' in a frame because it set 'X-Frame-Options' to 'DENY'.
jquery.js.xhtml?ln=primefaces&v=6.0:25 Uncaught SecurityError: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Sandbox access violation: Blocked a frame at "http://localhost:8080" from accessing a frame at "http://localhost:8080".  The frame being accessed is sandboxed and lacks the "allow-same-origin" flag.

Search google for a generic solution. Not PrimeFaces specific afaik
