How to display file name in Popover?

Hi!

I’m trying to display the file name in the popover preview when I quote one of its headers.

I’ve tried using the following snippet but the inline title variable displays the header name instead (see the pic below):

.hover-popover .inline-title {

}

What I’m trying to achieve:

Thanks in advance for any ideas!
