The question you are really asking is "where is the baseline of the 
button?", right?

Gecko puts the baseline of the button at the baseline of the button's 
text, and if the button is not auto-height the extra height is added (or 
removed) equally from above and below the text.

It looks like Chrome dev does the same unless there's no text in the 
button, in which case they put the baseline at the bottom margin edge 
(more inline-block-like behavior?).
