The new "Show popup upon feature selection" in the Map widget doesn't seem to be working properly. I have a map with valid popup configurations that display properly when I open the experience and click on a feature:

However, if I search for any feature, the popup shows blank:

Furthermore, now I can't see the popup for any feature in any layer, even ones I haven't searched on, until I refresh. Showing the popup on feature selection breaks the popups for the entire experience until it's refreshed.
This isn't limited to the search widget. Here's a brand-new session where I'm selecting from the Query widget:

It's not limited to one layer; it happens on all layers. I even tried spinning up a new experience and got the same behavior. Has anyone else come across this? Any thoughts, ExB team?
