Sometimes, the BrowserWindow's ready-to-show is fired before the ReadyToShow event handler of CSharp object is synced and registered onto the BrowserWindow JavaScript object.
In this case, the ReadyToShow event handler will never be executed.

In the following code, the browserWindow would never be shown:

var browserWindow = await Electron.WindowManager.CreateWindowAsync(new BrowserWindowOptions
{
    Width = 1152,
    Height = 864,
    Show = false
});

browserWindow.SetTitle("MyApp");
browserWindow.OnReadyToShow += () => browserWindow.Show();

This case occurred randomly and especially more frequent on Windows systems.
It seems by adding some status caching in BrowserWindow.js and invoke the event handler immediately if the event handler is bound after the 'ready-to-show' has been triggered once, we can solve this problem.
