When I have two tabs open and click on a link in one and switch to the
other, the tab I switch to has keyboard focus until the page in the other
tab is fully loaded. Then suddenly that tab steals the keyboard focus.
First I thought that keyboard focus was just lost, but when you switch to
the tab with the newly loaded page, you can see that the things you tried
to do with the keyboard happened in this tab.

Example (of how I discovered it): Open two tabs, both showing
http://www.advogato.org. Click on the link Recent Diary Entries and switch
to the other tab. Because Recent Diary Entries page is pretty big you can
use the keyboard on the other page for some time, until the diary page is
fully loaded and receives keyboard focus.

My first galeon bug report. How did it go? :)
