Links to posts in iframe doesn't work

Hi, I have a problem with with links in iframe with embedded comments.

When I embed comments for topic on my site, some of links doesn’t work. As You can se on below screen:

  • “Continue discussion” link works and after click topic page on discourse is opened in new tab
  • Other links (in case we have some comments and replies) after click doesn’t work (after debug: they have data-link-to-post=“123” attribute and redirect after click is blocked in javascript)

Please help, is there an option to allow this links working?
