1. In Safari 4, Navigate to https://bugs.webkit.org/enter_bug.cgi?product=WebKit
2. Cmd-+ to activate full-page zoom
3. In the "Version" listbox, click the middle entry ("525.x (Safari 3.2)")
--> Notice that the click does not select anything.

Cmd-- to zoom back down, and the listbox starts responding to clicks correctly again.

I found the same problem using QtWebKit (tested on versions 4.5.1, 4.5.2 and 4.5.3).

Very easily reproducible... open the following HTML:
<select size="3">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>

Then set full-page zoom to something like 50%. After that you can't select any option.

Note that the problem only happens with <select> tags with the "size" attribute greater than 1.
