For our client plugin(remote plugin) in vcenter, the iframe sandbox attributes has "allow popups" in vcenter 7.0 U2 whereas the sandbox doesn't have "allow popups" attribute in vcenter 6.7 U3.

Could you confirm if it is allowed in vcenter 6.7 ? If not, is there a way to enable the same? Any suggestions would be helpful. Thanks in advance.

This is the error that we see for vcenter 6.7 when we try to open a page that is supposed to open in a new tab:

"Blocked opening '//<>/index.html' in a new window because the request was made in a sandboxed frame whose 'allow-popups' permission is not set."
