HTML window.close() not working

[MauriceVeraart]

Expected behaviour

When I do

   function stop() {
        // some out animation
        setTimeout(function(){ window.close(); }, 2500);
    }

the HTML producer get's destroyed (2.1.8 NRK version )

Current behaviour

When I look in DIAG the producer stays 'eating memory'

Environment
