A Yellow Dot On Google's Top Bar?

Matt McGee noticed a weird thread at Yahoo Answers where one or two users are noticing a yellow dot just under the search box of the new Google search bar.

I personally cannot replicate it but the user took a screen shot and here is a cropped version:

One person gave a bit more technical details on where the dot is in the HTML.

The dot is in it's own html div:
<div id="ucs">
<div style="margin-bottom:12px">
<table class="ts" align="center">
<tbody>
<tr>
<td style="background:#ff9;padding:5px;text-…
</td>
</tr>
</tbody>
</table>
</div>
</div>

Have you ever noticed this? I haven't.
