Using hbspt.forms.create function, suddenly redirecturl is not appearling in lightbox

[#1]

FOr several years some of the customers what the form for download to appear in a lightbox (fancybox) , the redirect URL was served in the same box however the latest forms.js changes put a stop to it, instead it replaces the original url (like target=_top) the on form.ready feature to set target to self or blank does not trigger, any clue what is going wrong, and how to solve this little mistery?

Hi @walter_l,

I'm not sure I'm totally clear on the behavior you're describing. Are you trying to load the redirect_url in an iframe? Do you have an example page that illustrates the behavior you're seeing?
