Edge: Let WebView2 handle opening new windows by default

With Edge, just as IE did, supports opening new windows on its own,
unlike the WebKit implementation on Linux/macOS.

Therefore, to maximize compatibility with IE as the previous default,
also let WebView2 handle opening new windows by default.

Fixes #1845.
