Why do we need it?

I think this is necessary to allow RWHVA::OnKeyEvent() create a correct
NativeWebKeyboardEvent object (see the code snippet below). There might be a
better way to do so, though.

 617 #if defined(USE_X11)
 618     if (!event->native_event()) {
 619       // Send a fabricated event, which is usually a VKEY_PROCESSKEY IME
event.
 620       NativeWebKeyboardEvent webkit_event(event->type(),
 621                                           false /* is_char */,
 622                                           event->GetCharacter(),
 623                                           event->flags(),
 624                                           base::Time::Now().ToDoubleT());
 625       host_->ForwardKeyboardEvent(webkit_event);
