The solution is quite simple, though: use the common way to declare line-height:

line-height:40px;

If a parent element is overflow:hidden, any of its children or grandchildren should be invisible if they fall in the overflow area.

In IE 6 and 7 beta 2, if a child has position:relative, its contents are totally visible although the parent is overflow:hidden
