<select>s aren't rendered according to the CSS in the way that <button>
contents are. Consider:

"As I interpret it" is "as it's defined in CSS". If the definition is
wrong, let's fix it, but as currently defined, <button> isn't a replaced
element by the CSS definition.

In the case of <img>, that's a bug, as far as I can tell. I don't see what
in CSS would justify this behaviour.
Maybe it's a bug for <button> as well, and maybe "replaced element" needs
to be redefined so that it's not about the contents but about the element
having intrinsic dimensions that override normal sizing behaviour.

Sure, that'd be great. (Either place is fine.)
