# This code is an awful hack that is done here only because
# PhantomJS 1.x incorrectly handles "use strict" statement in
# some cases leading to sinon spy executing in a non-strict
# mode, even though it explicitly says otherwise. Since the
# people still use PhantomJS 1.x, this has to remain here
# to add another wrapper with another "use strict" on top
# of UMD bundle packaged by browserify.
