Describe what the issue you are experiencing is.

It seems webviews stop working if you don't use them for a while. Maybe a time out if we stop using the web engine ?

Provide reproducible steps for this issue.

1. Create a new empty project.
2. Import Unity Web Browser Basic samples and drag and drop UnityWebBrowser prefab into the scene.
3. Play
4. Wait for 10 minutes without using the webview (I don't know if the bug can be trigger quicker :/ )
5. Focus the search field, enter a random url and click on the button to start searching.
6. It doesn't work, I got this errors logs :

[Web Browser]: [Engine]: Uncaught exception occured in the entry point!
System.IO.IOException: Unable to read data from the transport connection: An established connection was aborted by the software in your host computer
