That's the content box, yes.

Basically in this case it means that the child (the anonymous block we
put inside the button) said "I'm not computing my ascent unless I have
to; please call GetBaseline() on me to find out what my ascent is". If
ascent is not set to ASK_FOR_BASELINE then it's already set to the
ascent of the child.

In Gecko's implementation of buttons there is always an anonymous block
child wrapping the button contents.

Well, the larger point of "button baselines need to be defined" kinda
does, either here or on www-style...
