Can't tab focus the file queue (not FF)

Can't tab focus the file queue at all.

Steps to Reproduce:

1) Open either of the version of uploader from the daily build site:
http://build.fluidproject.org/fluid/sample-code/uploader/inline/index.html
http://build.fluidproject.org/fluid/sample-code/uploader/pop-up/index.html

2) Add some files to the file queue

3) notice that you can't tab focus the file queue, whether the scrollbar is showing or not
