Also, besides Safari and IE not supporting <input usemap>, Opera's
behavior of it is differs depending on whether the input is in a form
or not. (If it's not in a form, it doesn't behave like a button.)

Also, in Opera, if the map the input is associated with has 2 area
elements, each with their own title attribute, when hovering over the
coordinate range for the second area element in the image, Opera won't
display a tooltip.

For example, see http://shadow2531.com/opera/testcases/imagemaps/001.html
Hovering over each square should show a title tooltip, but the bottom
red one fails in Opera. Check in FF to compare.

I've only used <input usemap> for test cases and can't think of any
good use for it since it's not even supported well.
