1. As soon as you start typing in the form, the form will prerender the booking page(where redirect is supposed to happen)
2. Clicking on submit will open the prerendered/being prerendered iframe in the modal
3. Changing the form response and clicking submit, will re-submit the response and reopen the modal with the updated data(update slots call, updated prefill fields)
4. Clicking submit again without changing the form response will just re-show the hidden modal(as long as threshold of 1 min since last time the modal was shown is met). But, in case of an error it iframe always tries to rerender. Trying adding an invalid email to see the error
