Disable hiding the off-canvas upon window resize.
user
```coffeescript
# Extend the "offCanvasWrap" directive in "angular-foundation" to disable hiding of the off-canvas
# upon window resize.
#
# In some browsers for mobile devices, the address bar is automatically hidden when scrolling down
# the page. This is not workable if the height of the contents of the off-canvas exceeds the height
# of the screen, because the latter portion of the contents stays hidden to the user.

angular.module('mm.foundation.offcanvas').directive 'offCanvasWrap', ($window) ->
  {
    restrict: 'C'
    priority: 1
    link: ($scope, element, attrs) ->
      win = angular.element($window)

      # Get the scope used by the "offCanvasWrap" directive:

      isolatedScope = element.isolateScope()

      # Unbind hiding of the off-canvas upon window resize.
      win.unbind('resize.body', isolatedScope.hide)
