STR:
1. Start a webserver on localhost:port that serves a dummy index.html
2. Register a custom http protocol.
   
   ``` js
   electron.protocol.registerStandardSchemes(['foobar', 'http', 'https']);
   
   app.on('ready', function() {
     electron.protocol.registerHttpProtocol('foobar', (request, callback) => {
       const redirectPath = `http://localhost:port/index.html`;
       callback({ method: request.method, referrer: request.referrer, url: redirectPath });
     }, e => { if (e) { console.log(e); } });
   });
   ```
3. Either through devtools, or via some js in our index.html, have a single line that does `fetch('http://localhost:port/index.html')` or anything else from our server.

Results: as soon as `fetch` is called, the webview becomes black, and the devtools crash if they were open. No other visible error or stdout.

If devtools were open, they show this message: "Devtools was disconnected from the page.
Once page is reloaded, DevTools will automatically reconnect."
