For Mozilla and Opera we need to patch their style implementation.

Mozilla thinks a listbox with style='width:100%' means the listbox width must accommodate 
the widest element in the listbox. In fact '100%' should refer to the page width, 
meaning the listbox should be as wide as the page. That's how it works for textboxes.

Mozilla furthermore ignores listbox style='height:100%'.

Opera thinks a listbox with style='height:100%' means the listbox height must accommodate 
the total # element in the listbox. In fact '100%' should refer to the page height, 
meaning the listbox should be as tall as the page. An empty listbox with style='height:100%' 
is 1 px. high in Opera!
