This tests that the specified height is honored (*) for <input> and <button> elements.
(*) The Mac ports ignore the specified height for <input type="button"> elements unless a border and/or background CSS property is also specified (see the fifth button below). Disregarding padding, they render the button with a height equal to the height of the font used for the button label.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
