// CEF sends a close notification to the application's top-level window

|
// 7. Application's top-level window receives the close notification and

|
|
|
// calls TryCloseBrowser(). TryCloseBrowser() returns true so the client
|
|
|
|
// allows the window close.
|

|
|
// 8. Application's top-level window is destroyed. 9. Application's
|
|
|
|
// on_before_close() handler is called and the browser object
