With previous change, KeyboardEvent is dispatched even when invisible window has focus. However, nsRootWindow::GetControllerForCommand() returns controller for focused window even when the window is invisible because it uses nsFocusManager::GetFocusedDescendant() to retrieve focused window. Perhaps, we can assume that users won't expect to do something with invisible window when they type some keys. Then, nsRootWindow::GetControllerForCommand() should return controller for visible ancestor window if focused window is invisible. This patch makes nsFocusManager::GetFocusedDescendant() can return only visible descendants. However, it already has a bool argument. Therefore, it should have a flag instead of adding new flag. Most changes of this patch is replacing its callers. Then, nsRootWindow::GetControllerForCommand() and nsRootWindow::GetControllers() should have a bool flag if it should return controller(s) for visible window. This patch adds a bool flag for it. Fortunately, the interface isn't scriptable. Finally, this patch makes nsXBLPrototypeHandler::DispatchXBLCommand() and EventStateManager::DoContentCommandEvent() retrieve controller for visible window since they are always handles user input.
