Calendar card (Google): Clicking on item doesn't open reminder details anymore?

I remember about a year ago when I would click on an item in the Calendar card such as an Amazon delivery reminder… it would open a window displaying details about the delivery including tracking info link, etc.

Now, when I click on items in the Calendar card, nothing happens. I think this feature stopped working for me after I upgraded to the new Calendar integration. Is there a way to turn this feature back on?
