Status: RESOLVED WORKSFORME

(Core :: Layout, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050404 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050404 Firefox/1.0+

Consider this example: 

<div style="overflow:hidden">
<select>
<option value=1>A</option>
<option value=2>B</option>
<option value=3>C</option>
</select>
</div>

If you click on the selectbox, the dropdown part isn't showing. You can select
the selectbox though, and use the arrow keys etc. Seems to be a regression from
a few days back.

Reproducible: Always

Steps to Reproduce:
See the included example html.



I'm using a recent nightly. Haven't tried yet with the latest, because there
where some work-affecting bugs lately.
