Hi,
I did not have “Full info on hover” selected. Please see that it is not marked as selected in your video (attached screenshot). When you select one of them there is a blue frame around it and if you see your video there is not a blue frame around “Full info on hover”.
I had “Show summary on hover” selected which was just below “Full info on hover”.
Anyway, either I select “inherit” or “show summary on hover” in the Product Grid element, it does not work. Please, check it.
Now it is selected “inherit” (see screenshot) and there is the frame in blue around it.
