Build ID: 20130208031053

Steps to reproduce:

It is always possible on a Lo-DPI screen or if the Hi-DPI screen is right of Lo-DPI screen.


Expected results:

The option should be selectable by click.

In a little more detail: If you press -and hold- on the <select>, and drag to choose an option, that works fine. And if you click to open the menu, then move the mouse up and down over it, the options highlight as expected when the mouse passes across them. Yet clicking to select one fails. That's really weird.

Moving this to Widget:Cocoa for now, though it might turn out to be a problem at a higher level in platform-independent code.
