javascript - Set cookie's secure flag in IE11 (client-side) -

as seen in screenshot, setting in dev console ignores flag.

document.cookie="test=that;secure" 

adding domain or path not seems either. (another answer saying made work)

this works flawlessly in chrome, firefox , safari.

i'm not sure see point in setting secure flag locally if possible. cookie flag should set web application or webserver running in front of application.
