As you can read in the referred MDN article, there is no reason to assume 
that the dimensions specified in the third argument of window.open() specify 
the popup *window* size.

If instead you meant that the popup window’s observed *viewport* size 
differed from the size that you specified, you should have said so
instead of just claiming a bug.  Also, you have neglected to describe
your measuring method.

JFTR:

In Chromium “Version 57.0.2987.98 Built on 8.7, running on Debian 
stretch/sid (64-bit)”,

  var w = window.open("about:blank", "", "width=640,height=480");

consistently displays a blank popup window whose viewport dimensions are

  w.innerWidth  === 414
  w.innerHeight === 480

here with Mobile View with “iPhone 6 Plus 414 × 763” enabled (consistently 
w.innerWidth === 640 otherwise, as the full screen has 1366 × 768 pixels and 
allows for it).

And I do not think that is a bug either.
