[Feature]: Allow fullscreen element programmatically

[Poker-sang]

Describe the feature/enhancement you need

Although browsers have security concerns about prohibiting full-screen elements without user gestures, programs with embedded WebView2 sometimes need to allow the user to click on an external button to go fullscreen on an element.

Is it possible to make an element fullscreen via AdditionalBrowserArguments or CoreWebView2.PermissionRequested?

The scenario/use case where you would use this feature

Taking over the web player with WinUI3

How important is this request to you?

Impactful. My app's user experience would be significantly compromised without it.

Suggested implementation

Allow fullscreen an element via AdditionalBrowserArguments or CoreWebView2.PermissionRequested

What does your app do? Is there a pending deadline for this request?

No response

Add the moment I had to add a button in my dialog which causes the html to show a popup, maximized to the display.
