electron 2.0.x Sandbox Bug

In Electron 2.0.0 and 2.0.1, remote objects are being dereferenced prematurely in a <webview> that is both sandboxed, and has a preload script. While the first webpage loaded does not exhibit this problem, subsequent pages will.

This application is a simple demonstration of the issue. It will:

• Open a BrowserWindow containing a <webview> that loads google.com.
• Open the dev tools for that BrowserWindow, so that errors against remote object errors can be seen on that window's console.
• Log object dereferences on stdout.
• Start an interval timer that polls webview.getId().

The Google landing page should not exhibit any errors, with each call to webview.getId() succeeding. After navigating to another page, the <webview>'s webContents will shortly be dereferenced (typically within 5-10 seconds), and errors will be logged.

To verify that this behavior does not occur with sandboxing turned off, or without a preload script, modify the commented section of lib/index.js.
