As I read the quote from the spec there is no recommended behaviour
(should) under CSS 2.x rules. Browser behaviour varies, Opera and IE
behave one way, Gecko another, regarding form elements afaics none are
wrong. (FF 1.5 does behave in a non spec compliant manner when such
styling properties are applied to an image.)

I presume that a form element is considered a replaced element, I'm not
sure if they are considered to have intrinsic dimensions, afaics the 2.1
WD is ambivalent on this:

http://www.w3.org/TR/CSS21/conform.html#q1
States: "Replaced elements *often* have intrinsic dimensions:"
And: "In CSS 2.1 it is assumed that *all* replaced elements, and only
replaced elements, come with intrinsic dimensions."

(Emphasis mine)
