Parent window loses control of child when child window is opened in IE mode

// example assuming https://protect-us.mimecast.com/s/yicWCo2KpksGpzoSznOV7?domain=google.com is in my IE mode site list

var win = https://protect-us.mimecast.com/s/Bf9sCpYKrlhLE8lcYnXgE?domain=window.open(url, 'secondMonitor', `resizable=1, scrollbars=1, fullscreen=0, height=500, width=500, left=100, top=0, toolbar=0, menubar=0, location=1, status=1`);

setTimeout(() => {
// window does not navigate to new url
win.window.location.href = 'https://protect-us.mimecast.com/s/2yKICqx5wmTr654UE_GqH?domain=google.com 2'
}, 5000);

setTimeout(() => {
// window does not close
win.close();
}, 10000);
