I would recommend having a look at these articles from Nielsen Norman Group for thoughts on this:

Did they need information available in two different modals?įrom there I would ask if this modal is the right tool for this situation or not.Did they want compare with information on the previous page and now hidden by the modal?.Does the modal behaviour prevent them from doing something else they'd like? Examples:.Is there not enough 'shadow' between the modal and the page it's superimposed on?.Does the window appear at the top of the page above where the user has scrolled to?.Is there something in the interaction or visual design that causes confusion? Examples:.What were users' expectation when they clicked?.If users are having challenges, I would start by enquiring further: Have you studied your users' behaviour to see if they are disoriented or surprised when they click the link/button and get a modal? And yet I can't help but wonder if this is a solution in search of a problem. It feels like we should want to set users' clear expectations with something an icon, like you suggest.
