1461612 - In Responsive Design Mode window.open() doesn't return reference to the newly created window

Status: RESOLVED DUPLICATE of bug 1379834

(DevTools :: Responsive Design Mode, defect)

Description

[Sander Aarts]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36

Steps to reproduce:

Load a page that opens a new window using window.open() and writes some content to it:

var _test = window.open('', 'test', 'width=800,height=600,resizable,scrollbars=yes');
_test.document.write('Test');
_test.document.close();


Actual results:

In Responsive Design Mode it opens a new tab (the width and height are ignored) which stays empty. The Developer Tools Console tab shows the following error:

TypeError: _test is null



Expected results:

It should open a new window with the given properties showing 'Test'. And when not in Responsive Design Mode it does so. When the window 'test' was already opened previously, then reloading the parent window in Responsive Design Mode does not have this error.

Whether the parent window is loaded in Responsive Design Mode or not should not make a difference.
