When calling a window's `webContents.downloadURL(URL)` method if the specified URL returns a 404 the `will-download` event on `webContents.session` does not fire and instead a dialog pops up asking the user to save an html file (the contents of the 404 page).

Is this expected behavior and is there any event I can listen to or some other way to get around this? I'd like to handle the error differently if possible.

Thanks
