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!
