Blank screen on loading pdf from URL `http://docs.google.com/gview?embedded=true&url=${url}`

Bug description: Sometimes pdf is rendered fine and sometime it’s just blank screen, debugged it many times but always the url and headers are same. Don’t know what is causing the issue.

To Reproduce: let url = http://docs.google.com/gview?embedded=true&url=${url};

<WebView ref={(ref) => { this.webviewReload = ref; }} source={{ uri: url, headers: headers, }} incognito={true} style={{ flex: 1 }} onLoadEnd={() => this.setState({ loaded: true })} />

Expected behavior: Pdf should always render successfully.
