javascript - Modernizr + Bootstrap 2/3 => browser's scrollbar disappears -

-

i use twitter bootstrap 3.0-rc1 combining modernizr 2.6.2. (the issue reproducible bootstrap 2.x.x)

i struggled find why browser didn't show scrollbar, traditionally on right side. (of course tried minimize browser's window in order see it)

i first found this post, potentially linked issue, since use navbar component of bootstrap.

i find when remove second line of snippet: 

<link rel="stylesheet" media="screen" href="stylesheets/bootstrap.min.css"> <script src="javascripts/modernizr-2.6.2-respond-1.1.0.min.js" type="text/javascript"></script>

the whole works meaning scrollbar appears.

is normal behavior modernizr remove scrollbar regarding context?
