[WebView2] Limitations on the url used for source?

[DevTKSS]

Hey, I am looking into the WebView2 docs of uno and just inserting a sample url for a auth request to the source gave me a warning I dont now about, the docs dont mention this...

e.g. thats the sample string, I took from a Quick Start guide for oAuth request (no actual credentials there!)

 <WebView2 x:Name="MyWebView"
           Source="https://www.etsy.com/oauth/connect?response_type=code&redirect_uri=http://localhost:3003/oauth/redirect&scope=email_r&client_id=1aa2bb33c44d55eeeeee6fff&state=superstring&code_challenge=DSWlW2Abh-cf8CeLL8-g3hQ2WQyYdKyiu83u_s7nRhI&code_challenge_method=S256" />

and this warning I am getting as soon as I type in a url encoded string like that with including an & char.

I never worked with uri so far, but never noticed any of those samples doing a semicolon at the end?

has somebody more information?

@MartinZikmund The docs dont tell us about this char limitation 🤔
