Searchbar increases window size when bottom of page is reached

[Rasmus]

Binary package hint: firefox-3.5

How to reproduce bug:
Go to a homepage with a scrollbar eg. www.jp.dk.
Search for something on the page by pressing CTRL+F eg. influenza
Press Next until search hit bottom of page.

The windows size has now increased and you can no longer see the scrollbar.

I have a 1024X768 resolution monitor.

If I disable the danish language in FF the bug is gone.
It looks like the window size is increased because there isn't enough room for the danish text: "Bunden af siden blev nået, ..." (in english: End of page is reached... (or something like that)). See attached screenshot.
