Control filter popover hiding?

[juliusn]

In the searching and filtering example, when a filter input has been opened, clicking outside the popover hides it.

I'm trying to follow the example, but the popover stays visible after clicking outside of it. I can only close it by clicking on the filter icon.

Why is the behavior different in these two examples? How do I control the hiding behavior of the popover?
