What steps will reproduce the problem?
1. open command line mode with 'o' or 't'

What is the expected output? What do you see instead?
Expected the command line to be shown and to be focused.

The command line is shown but is not focused automatically.
A click of the mouse to the command line focuses the command line.

What is the output of :yank :version, or the exact Pentadactyl version and
Firefox build identifier (see the about: page)?
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.15) Gecko/20101028 Iceweasel/3.5.15 (like Firefox/3.5.15)
Tried both "button on main page" version and 2010-11-12 nightly; same result.

Can you reproduce this problem with all custom configuration and plugins
disabled (i.e., running firefox -pentadactyl '+u NONE')?
Yes, reproducible.
