Some functionalities of the "Nearby" map app template seem to be limited when embedding into a storymap. When the map is open in full screen, the user is able to click on a point within the search area, and the sidebar scrolls to the information of that point. When embedded within a map app, this functionality does not seem to work. Is there a toggle to allow this, or a bug perhaps? Added a quick snippet below in a video.
It looks like a bug in the app when embedded. The app logic looks to the parent to figure out where to scroll and the frame is messing this up. I'll look into the app code and see if we can get a fix in for this behavior.
