[Problem/Bug]: NavigateToString does not request CoreWebView2BasicAuthenticationRequestedEventArgs #5393
Description
What happened?
We have a proxy connection, but authorization is triggered only if the navigation was to an external source. If we make a code:
Webview2.CoreWebView2.NavigateToString("<html><body>IMG: <img src='https://www.google.com/tia/tia.png'></body></html>");
Then we have a 407 error in devtool, but there is no request to the proxy in automatic mode and the CoreWebView2BasicAuthenticationRequestedEventArgs function is not called in any way.
It's too dangerous to use crutches with authorization first to .Navigate("https://google.com"), and then to perform NavigateToString, and there may be pitfalls.
Importance
Moderate. My app's user experience is affected, but still usable.
