 Then that phrasing is incorrect, please file a bug. The multipliers are
 (and are intended to be) separate.

 I probably won't make changes w/o knowing all of the exact effects they
 have.  I could test, but what would your example of inner height = 700
 actually prove?

 It would narrow down the problem, but it's probably unnecessary, because:

 > I only used JS because the Browser Spy (& other) test sites can't get
 screen size unless JS is enabled.

 '''Use a fresh TBB installation, with no configuration changes, for
 testing your window size.'''

 > That's why JS is enabled in TBB by default in NS.  Don't get me wrong -
 I keep it off by default.

 I keep it on. Either way, the one thing you must never do is to
 selectively enable/disable it for only some sites, because this will
 identify you: https://www.torproject.org/docs/faq#TBBJavaScriptEnabled
