<h3>Log Message</h3>
<pre>Test listbox clipping to contents rect
https://bugs.webkit.org/show_bug.cgi?id=156265
Reviewed by Simon Fraser.
These tests create some <select><option></option></select>s with padding.
These list boxes use the zapfino "f" character (because it draws wildly
far outside of its layout box) to create a case where text inside the list
box would naturally intersect with the padding. This overflow should be
clipped so that the padding is undisturbed.
