Hi.
Trying to use modals to show different webpages I found that some sites seem to block its rendering on popups/iframes. For exemple:
Refused to display 'https://www.bbc.com/xxxxxx' in a frame because it set 'X-Frame-Options' to 'DENY'.
Refused to display 'https://www.aljazeera.com/xxxxx' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.
