Current behavior:

The no-scroll class is not given correctly due to the fact that the height is incorrectly calculated. We need to use the .outerHeight() function instead of the .height() function as we do in the _updateContentMaxHeight function.

With .height(): https://a.supportally.com/v/iwjyIm (I can't scroll even though the content is there)
With .outerHeight(): https://a.supportally.com/v/Ay4WIg
