dom tame poc

[weizman]

works nicely, still needs to tame addEventListener (EventMessage.prototype window leaking props).
test by:

• yarn dist
• lookup document.createElement("div"); under the entire dist/chrome folder
• pick the one within common-1.js (should have the string "50px" right after it)
• paste the following code right after it
• visit the extension with your devtools open

;(function test1(){ debugger;
    try {
        document.createElement('a').ownerDocument.location
    } catch (e) {
        e.message === 'NOT ALLOWED(document): location';
    }
    try {
        document.createElement('a').ownerDocument.open
    } catch (e) {
        e.message === 'NOT ALLOWED(document): open';
    }
    try {
        document.createElement('a').ownerDocument.defaultView.alert
    } catch (e) {
        e.message === 'NOT ALLOWED(window): alert';
    }
    try {
        document.createElement('a').ownerDocument.body.getRootNode() === document.createElement('a').ownerDocument
    } catch {}
    try {
        document.createElement('a').ownerDocument.body.parentNode.parentNode === document.createElement('a').ownerDocument
    } catch {}
}());
