### Issue Details

* **Electron Version:**
5.0.0 to 8.0.0 beta7
* **Operating System:**
Windows 10

### Expected Behavior
The did-fail-load event should be fired.

### Actual Behavior
The did-fail-load event is not fired.

### To Reproduce
Add an event handler to the did-fail-load event.
Add an event handler to the certificate-error event and cancel the default handling. Then call the callback with false.
The did-fail-load event will not be fired.

```
mainWindow.webContents.on("certificate-error", (event, url, error, certificate, callback) => {
      event.preventDefault();
      callback(false)
});

mainWindow.webContents.on("did-fail-load", (event, url, error, certificate, callback) => {
      console.log("did-fail-load");
});
```

### Additional Information
loadURL returns a Promise, in the certificate error case this Promise will be rejected. The gist will show this too.

```
mainWindow.loadURL('https://expired.badssl.com')
  .then(() => console.log("success"))
  .catch(e => console.log("fail"))
```
