Edit: The reason seems to be a external_link_interception javascipt somewhere deep in SBM which occurs when clicking external links......

function(e) {
  e.preventDefault();
  e.stopPropagation();
  openExternalLinkInNewTab(element.href);
  return false;
}

How can i deactivate it in this case?

I think the issue may be that the HTMLJS widget becomes an embedded iframe.  Try one of the following options:

1. Add a URL control to your form.
2. Add a text field with a prefix and suffix to create the link.  Default the field to be your link text and use target="_top".  Like this.

Thanks for any help.
