    inspector: Destroy popovers on unmap
    
    As an implementation detail, the popover hooks the fade out animation
    on ::hide. Destroying the popover right away here is not a problem, but
    prevents the animation from actually running. ::unmap will be run after
    the animation is finished, so destroy the popover there.
