I will likely make WS_EX_NOACTIVATE the default and allow for customisation of IWindowInfo like in WPF. Anyone wishing to still use the default behaviour will be able to, though it doesn't really make much sense for it to be the default to me.

WS_EX_NOACTIVATE was made the default in https://github.com/cefsharp/CefSharp/commit/a7a73dc930f1ee2f39c40a170e9f795247b3e4e6

To re-enable activation by default then create a custom class that inherits from ChromiumWebBrowser and override the CreateBrowserWindowInfo method. Then it's a simple case of removing WS_EX_NOACTIVATE from WindowInfo.ExStyle

const uint WS_EX_NOACTIVATE = 0x08000000;

windowInfo.ExStyle &= ~WS_EX_NOACTIVATE;

If there is enough demand then I will add a bool Property that can be used to enable/disable activation. It's not clear that there is enough demand at the moment, most people asking how to disable window activation as it's an unexpected behaviour.
