Run the attached test. Click on the choicebox with selection item0 in browser. It will show the output as shown in attached screenshot.

 When we run the same test in standalone mode, it shows the choicebox correctly with upper arrow and lower arrow and the way it's shown is also correct. But in browser it's not the case.

I am running it on Win XP SP3 with Chrome version which we get online 4.1.249.1045(42898). The jre used is : 6u17 and fx is b32 of soma.
