Is your enhancement related to a problem? Please describe.
When the popover is open, the text cursor jumps into the filter input. There's a little arrow pointing to the insertion point but it's not really visually super-precise to let you know where exactly you're inserting.

Describe the solution you'd like
I would like to see a faux-cursor. I think it's a matter of inserting a temporary span and styling it up appropriately. It's actually probably best if it doesn't blink.
