This reverts commit 59a183aed82552462bb814fc13abb1f0217bca03.
With 0.11 this causes every <a data-toggle="dropdown"></a> to
require 2 clicks for opening - first click selects it, second opens.
There is not even a package for XStatic-Angular-Bootstrap 0.13 yet.
This patch either needs to be compatible with 0.11 and 0.13, or we
need a new 0.13 package and update global-requirements lower end
cap on it.
