Build Identifier: 

nsTypeAheadFind::KeyPress calls StopPropagation() but not PreventDefault() on
the DOM event. This omission causes nsWindow::OnKeyPressEvent() to return FALSE,
marking the key event as not consumed to gtk+. In turn, this makes other
handlers try to handle the event.

Reproducible: Always
Steps to Reproduce:
0. Start Epiphany (or any other gtk+ 2.x embedding client which has a window
with a menubar activatable with Alt+Letter), using gtk+ CVS HEAD from 2004-11-06.
1. Load a page
2. Type "/F" (without quotes)

Actual Results:  
File menu opens.

Expected Results:  
The first "F" in the page is highlighted, and menu not opened.

I see the code for escape and backspace the code uses PreventDefault but not
StopPropagation. I would have thought the same applies here, but it was
explicitly changed for bug 168281. CCing Kyle in case he knows why.

proposed fix

Neil, I just thought that StopPropagation() made PreventDefault() unnecessary.
Guess I was wrong.

No, they mean two completely different things... stopPropagation just means that
no further event listeners in the current event group (normal or system) will be
called. However frame event handlers and xbl keys have separate processing and
preventDefault is the only option to inhibit that processing.

If it works, I'd like to see preventDefault without stopPropagation.

PreventDefault without StopPropagation

Using only PreventDefault() without StopPropagation() appears to work fine too,
from a quick test in mozilla-browser and epiphany.
