Re: [CSS21] text-decoration on replaced elements that "contain text"

A related issue is ::first-letter when the button is display:block.

http://www.w3.org/TR/CSS21/selector.html#first-letter
"The :first-letter pseudo-element must select the first letter
of the first line of a block, ..."

According to https://bugzilla.mozilla.org/show_bug.cgi?id=229425
there are at least two implementations (IE,Opera) that applies
::first-letter styles to the first letter inside a display:block
button.

What is the correct behavior according to CSS 2.1?

Same question for ::first-line?
