Reviewed by Anne van Kesteren.
Per the specification [1], when an embed, iframe, img, or object element, or an
input element whose type attribute is in the Image Button state, has an align
attribute whose value is an ASCII case-insensitive match for the string
"center" or the string "middle", the user agent is expected to act as if the
element's 'vertical-align' property was set to a value that aligns the vertical
middle of the element with the parent element's baseline.
