If the renderer process crashes, and the user attempts to save the page, the browser process crashes (in debug builds) due to the following DCHECK: https://cs.chromium.org/chromium/src/content/browser/download/save_package.cc?rcl=2392358c4e0ff0396bd74cd7c78faa45634c73d3&l=1096

In a non-debug build, the download starts in the download tray, but is stuck at "Starting". This seems like a bad user experience. Perhaps the download tray could indicate that the page must be refreshed first?
