Reproducible: Always Steps to Reproduce: 1. Open a web page, for example lwn.net. 2. Click a link in the web page. 3. Click the Back button to go back to the home page. 4. Then, try to use PageUp, PageDown, Home, End, Up, Down, Left, Right and Space key, they are broken now. Actual Results: PageUp, PageDown, Home, End, Up, Down, Left, Right and Space have no effect. Expected Results: PageUp, PageDown, Home, End, Up, Down, Left, Right and Space should move the web page content accordingly. It works when I check out and compile it last time, so it's a recent regression.
