<h3>Log Message</h3>
<pre>RTL &lt;select&gt; forms are misplaced
https://bugs.webkit.org/show_bug.cgi?id=158810
&lt;rdar://problem/24847541&gt;

Reviewed by Eric Carlson.

AppKit made a change in Sierra that causes popup menus
to snap to a different point when the system language is RTL.
We need to be more explicit about what directionality
we want, and override the location of the popup based
on the text direction.

I also made a small tweak to the fudge offsets we use
in order to make button text and menu text to be
more consistent.

Unfortunately since this is just about the location
of the popup menu, it's unable to be tested in our
current infrastructure.
