1552751 - MessagePort should not work, silently failing, when created from removed windows.

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect, P2)

Description

[Andrea Marchesini [:baku]]

A script like this doesn't create active MessagePorts, but it should:

let ifr = document.createElement('iframe');
...

let w = ifr.contentWindow;
ifr.remove();

let mc = new w.MessageChannel();
