[Problem/Bug]: On NavigationStarting cancel the navigation did not work

[dfghj44444]

What happened?

I register an ICoreWebView2NavigationStartingEventHandler event and can work well, if I put_cancal true, the navigation will cancel. But one scene is weired, while the target site contains an invalid ssl certification, like "https://12306.cn", this navgation cannot be canceld, an will go to this page below.

@dfghj44444 For SSL interstitial pages you need you listen to add_servercertificateerrordetected event to cancel the request if the Navigation is not successful and failed with ConnectionAborted
