WebView inside WebView (aka BrowserView from Electron)

[Kadeluxe]

Is there something like Electron BrowserView available?

I want to do a "WebView inside WebView". Outer WebView is basically my app UI and inner WebView is actual web content that app displays. The reason for that is that I want to create a tabbed UI in my app so I want to switch inner WebViews based on current tab selected and that approach would allow me to make app UI using web technologies as well.

If not, any alternatives? Maybe Chromium's Out-of-Process iframes (OOPIFs)?

I saw WebView2Browser sample and it uses an interesting approach with separate WebViews for UI and content but this is still limited because UI WebView is not able to overlay content UI so it's impossible to render something "outside" of the blue rectangle.

Any ideas?
